Three Punchy Stats
- West Ham have won four and drawn two of their last six meetings with Portsmouth, meaning Pompey are without a victory across that entire head-to-head sequence.
- Jarrod Bowen recorded 20 Premier League goal involvements last season, scoring nine goals and providing 11 assists despite West Ham being relegated.
- Portsmouth won only six of their 23 Championship away matches last season, while their most recent six away league games ended with two wins, two draws and two defeats.

Portsmouth must match West Ham United’s discipline and avoid conceding cheap openings.
The Hammers are preparing for life in the Championship after relegation from the Premier League, while Portsmouth are looking to build on an 18th-place finish in the second tier. Cup football therefore arrives before either side has had much opportunity to settle into the new domestic campaign.
For West Ham, this is about demonstrating that a squad retaining considerable attacking quality can respond positively to relegation. For Portsmouth, it is an opportunity to test themselves against opponents who were operating one division higher last season.
West Ham Enter a New Era With Familiar Quality
Relegation inevitably changes the mood around a football club, but West Ham have at least managed to retain much of their squad.
Mateus Fernandes and Crysencio Summerville have departed for Tottenham Hotspur and Al Hilal respectively, yet captain Jarrod Bowen remains. That continuity is significant because Bowen was directly involved in 20 Premier League goals last season, scoring nine and assisting 11.
Those numbers underline just how important he can be to West Ham's attacking structure.
A goal involvement simply refers to either scoring or directly assisting a goal, so reaching 20 in a relegated side reflects substantial individual influence. Bowen was not merely finishing moves; he was also creating them.
His presence gives West Ham an obvious source of attacking authority as they adapt to Championship football.
James Ward-Prowse could also return, while the wider squad has so far responded encouragingly during the summer. West Ham are unbeaten across their last five matches when their four summer fixtures are combined with the 3-0 victory over Leeds United on the final day of last season.
That victory could not prevent relegation, but it at least offered a reminder of what this team can produce when the attacking pieces connect.
Portsmouth Arrive With a Point to Prove
Portsmouth's challenge is very different.
They finished 18th in the Championship last season and won only six of their 23 league matches away from home. Their recent summer sequence has also been difficult, with no victory across their latest five pre-season friendlies.
That does not mean Portsmouth lack attacking options.
Marko Milovanovic has arrived from Almeria after spending last season with Alverca, where he scored nine league goals from 18 starts. That is exactly one goal every two starts, an encouraging ratio for a player added to strengthen the centre-forward department.
Portsmouth therefore have a new focal point to integrate, but this match could test how quickly their attacking structure has come together.
Their final six competitive league matches from last season offer a more positive picture than their pre-season results. Portsmouth won four, drew one and lost one of those games, including a 3-1 victory away to Stoke City and a 1-0 success at Middlesbrough.
The ugly exception was a 5-1 defeat at Coventry City.
That inconsistency is important. Portsmouth have shown they can travel and win, but their away performances have also contained moments where the defensive structure has come apart dramatically.
Against a West Ham side carrying players accustomed to Premier League football, that margin for error becomes extremely small.
The Numbers Reveal Two Different Attacking Profiles
Across their longer recent samples, West Ham have averaged 1.23 goals per game from 53 goals in 43 matches, while Portsmouth have averaged 1.06 from 51 goals in 48.
Neither attacking output is extraordinary in isolation, but the way the two sides generate attempts offers more tactical detail.
West Ham have averaged 11.33 shots per match, compared with Portsmouth's 12.13. That means Portsmouth actually produce slightly greater shot volume.
Yet 74% of West Ham's efforts have come from inside the penalty area, compared with 65% for Portsmouth.
That difference matters.
Shots from inside the box are generally produced from more advanced attacking positions, so West Ham's lower overall shot volume does not necessarily mean less threat. Their ability to get attempts from closer areas may be more important than simply piling up speculative efforts.
Portsmouth average 3.92 blocked shots per game compared with West Ham's 3.53, suggesting the visitors frequently encounter defensive bodies before efforts reach goal.
For Portsmouth, creating shooting opportunities will not be enough. They need to ensure those efforts come from positions capable of genuinely troubling the West Ham defence.
Possession May Not Tell the Whole Story
Portsmouth's average possession stands at 50%, compared with West Ham's 44%.
At first glance, that might suggest Portsmouth are more naturally comfortable controlling the ball.
However, possession should never be confused automatically with territorial dominance.
West Ham's passing accuracy is higher at 80%, compared with Portsmouth's 75%, while the Hammers average 392.14 passes per match against Portsmouth's 369.21.
That combination is interesting. West Ham have recorded less average possession while still completing more passes with greater accuracy.
It suggests their matches have often contained periods in which they circulate the ball efficiently without necessarily controlling overall possession for long stretches.
Portsmouth, meanwhile, average more total attacks at 96.98 per game compared with West Ham's 90.51. They also hold a slight advantage in dangerous attacks, averaging 46.6 compared with 43.26.
The visitors therefore have statistical evidence that they can advance the ball frequently.
The challenge is turning that progression into something decisive.
This is where West Ham's higher proportion of shots from inside the box becomes relevant. Portsmouth may generate slightly more attacks, but West Ham have been more concentrated in where their shooting opportunities originate.
In cup football, that kind of efficiency can outweigh long periods of possession.
West Ham's Home Record Adds Weight to the Occasion
The London Stadium has been a relatively productive venue for West Ham recently.
Across their latest six competitive home matches, the Hammers have won three, drawn two and lost once.
Those results include a 4-0 victory over Wolverhampton, a 3-0 win against Leeds United and a 2-1 success against Everton. The only defeat in that six-game home sequence was 1-0 against Arsenal.
West Ham scored 12 goals across those six matches while conceding five.
That does not make this a straightforward assignment, but it does demonstrate that their home performances have often carried genuine attacking threat.
Portsmouth's most recent six away league matches have produced a perfectly balanced record of two wins, two draws and two defeats.
Unfortunately for anyone seeking a neat tactical narrative, the scorelines themselves were anything but balanced.
Portsmouth won 3-1 at Stoke and 1-0 at Middlesbrough, but also lost 5-1 at Coventry and 6-1 at QPR. Their other two matches ended 1-1 against Norwich City and Blackburn Rovers.
In other words, Pompey have demonstrated both resilience and spectacular vulnerability on the road.
Football loves contradiction. Portsmouth's away record provides enough of it to keep an analyst employed for weeks.
Defensive Reliability Could Decide the Tie
The broader defensive figures reveal weaknesses on both sides.
West Ham have conceded 73 goals across 43 matches, averaging 1.7 per game, while Portsmouth have conceded 70 across 48, an average of 1.46.
West Ham have managed only eight clean sheets in that 43-match sample. Portsmouth have recorded 10 in 48.
Neither side, therefore, enters with overwhelming evidence of defensive dominance.
That is why the individual attacking quality available to West Ham could become particularly influential.
Bowen is the obvious example, but his significance goes beyond goals. His 11 assists last season demonstrate creative output as well as finishing ability.
If Portsmouth defend too deeply, West Ham could gain territory around the penalty area. If the visitors push higher, space may emerge for attacking movement behind their defensive line.
Finding the right balance is likely to be Portsmouth's biggest tactical problem.
Discipline and Physical Intensity Could Become Important
West Ham have averaged 11.47 fouls per game across their 43-match sample, slightly above Portsmouth's 10.23.
The Hammers also average significantly more tackles, with 17.77 per game compared with Portsmouth's 13.54.
That difference points towards a potentially more aggressive approach without the ball.
West Ham's ability to regain possession quickly could be particularly useful against a Portsmouth side averaging nearly 97 attacks per match.
If the visitors are allowed to advance repeatedly and settle into possession, they have shown they can create attacking volume. Preventing those moves from developing may therefore require West Ham to contest second balls and midfield duels aggressively.
There is a cost to that intensity.
West Ham have collected 77 yellow cards and four reds across their sample, while Portsmouth have accumulated 89 yellows and two reds. Maintaining aggression without losing control will matter in a knockout setting where one careless moment can transform the entire contest.
Previous Meetings Favour the Hammers
West Ham have not lost any of the last six meetings between these sides.
They have won four and drawn two, including victories by 1-0, 4-3, 2-0 and 4-1.
The most recent meeting finished 1-0 to West Ham in January 2012, while Portsmouth's previous visit to West Ham produced a remarkable 4-3 contest.
Four of the last six meetings have nevertheless produced fewer than three total goals.
That historical pattern is interesting because it contrasts with some of Portsmouth's more dramatic recent away results.
Nobody should assume another 4-3 merely because these clubs managed one previously. Football has enough chaos already without demanding sequels.
Milovanovic Gives Portsmouth a New Dimension
Milovanovic's arrival offers Portsmouth one clear route towards changing their attacking output.
Nine league goals from 18 starts last season represents an efficient scoring return. The task now is transferring that threat into a new team and a new competitive environment.
West Ham's defensive record means Portsmouth should not approach the match believing chances are impossible to create.
The Hammers conceded an average of 1.7 goals per match across their 43-game sample and allowed opponents to score in 33% of those fixtures without West Ham themselves finding the net.
Portsmouth, meanwhile, scored in 35 of their 48 matches, equivalent to 73%.
That is a useful reminder that the visitors are not simply travelling to London to absorb pressure.
Their chances of making the contest uncomfortable are likely to depend on whether they can turn possession and attacking volume into high-quality opportunities for players such as Milovanovic.
Bowen Remains the Obvious Difference-Maker
For all the tactical detail surrounding the game, Bowen is difficult to escape.
Nine goals and 11 assists in the Premier League last season represent a level of individual productivity that Portsmouth must somehow contain.
West Ham retaining their captain following relegation is therefore hugely important.
This is also why reducing the match to a simple contest between a relegated Premier League side and a Championship team would be lazy.
West Ham's status has changed, but much of their squad remains intact. Portsmouth are not facing an entirely reconstructed side stripped of its attacking identity.
Bowen gives the Hammers continuity at precisely the moment when relegation could otherwise have produced uncertainty.
T. Souček is unavailable with an ankle injury, while G. Cornet is dealing with muscle fatigue, so West Ham do have absences to manage. Even so, keeping their captain provides a central figure around whom their attack can continue to operate.
A Cup Tie With More at Stake Than August Usually Admits
Officially, this is simply the first round of the Carabao Cup.
Emotionally, it could feel considerably more significant.
West Ham are beginning life after Premier League relegation and will want evidence that the quality retained within their squad can translate quickly into positive performances.
Portsmouth arrive needing to prove that last season's 18th-place Championship finish does not define what comes next.
The tactical contrast should make the match compelling.
Portsmouth produce slightly more shots, more total attacks and more dangerous attacks on average. West Ham complete their passes more accurately and generate a much higher percentage of shots from inside the penalty area.
That makes this a contest between volume and location, territory and efficiency.
Portsmouth cannot afford to mistake possession for control. West Ham cannot assume superior individual quality will automatically solve every problem.
The hosts have the stronger recent head-to-head record and an encouraging six-match home sequence, but Portsmouth's competitive form towards the end of last season included four victories from six and two notable away wins.
For West Ham, the challenge is to convert technical superiority into pressure where it matters most: around the Portsmouth penalty area.
For Portsmouth, the challenge is nastier. They must survive that pressure while still committing enough players forward to threaten a defence that has hardly been impenetrable.
That tension should give the London Stadium an edge. It is the first competitive hurdle of a new season, but for two clubs with different ambitions and different scars from the previous campaign, it already feels like rather more than that.
Key Tactical Mismatch
74% of shots generated from inside the penalty area, driven by Jarrod Bowen’s 20 direct goal involvements.
Conceded 70 goals across 48 matches, including recent heavy away defeats of 5-1 at Coventry and 6-1 at QPR.

⚔️ Pick 1: West Ham to win and both teams to score @ 9/5
West Ham enter this Carabao Cup tie unbeaten in their last five matches, having closed their Premier League campaign with a 3-0 victory over Leeds United before recording four summer friendly performances without defeat. The Hammers have maintained strong attacking output at the London Stadium, winning three of their last six home matches while scoring 12 goals and conceding five.

Portsmouth offer genuine counter-attacking threat despite winning just six of 23 Championship away games last season. The visitors scored in 35 of their 48 matches across the campaign, representing a 73% scoring rate. Portsmouth average 96.98 total attacks and 46.6 dangerous attacks per game, while new signing Marko Milovanovic arrived after scoring nine league goals from 18 starts for Alverca. West Ham conceded 73 goals in 43 matches last season—an average of 1.7 per game—and recorded only eight clean sheets. With Portsmouth showing capable goalscoring frequency and West Ham continuing to concede regularly, backing West Ham to win alongside both teams finding the net aligns with both teams’ established statistical trends.

Conceded 70 goals across 48 matches, including recent heavy away defeats of 5-1 at Coventry and 6-1 at QPR.
🎯 Pick 2: West Ham vs Portsmouth 3-1 @ 9/1
A 3-1 scoreline for West Ham reflects the combination of home attacking strength and Portsmouth’s recent away volatility. West Ham scored 12 goals across their last six home matches at the London Stadium, including multi-goal victories against Wolverhampton (4-0), Leeds United (3-0), and Everton (2-1). The Hammers average 392.14 passes per match with 80% passing accuracy, allowing them to establish central control and direct 74% of their 11.33 shots per game into the penalty area. With Jarrod Bowen involved in 20 Premier League goals last season and James Ward-Prowse returning to midfield, West Ham hold sufficient technical dominance to generate multiple scoring opportunities against a Championship defense.
Portsmouth’s recent away fixtures highlight significant defensive openness alongside consistent goal creation. Across their last six competitive away league games, Portsmouth won 3-1 at Stoke City but suffered heavy defensive collapses, losing 5-1 at Coventry City and 6-1 at QPR. Portsmouth conceded 70 goals in 48 matches last season while managing only 10 clean sheets overall. However, Pompey average 12.13 shots and 46.6 dangerous attacks per game, and scored a 3-1 away victory of their own during their late-season run. Given West Ham’s average of 1.7 goals conceded per match and 11.47 fouls per game, Portsmouth possess enough attacking volume to score once, while West Ham’s superior box presence points toward a 3-1 home win.
Risk Factor: Four of the last six head-to-head meetings between these teams produced under 2.5 goals, and West Ham are missing key players T. Souček and G. Cornet.
