Rayo Vallecano host Alaves at the Estadio Municipal de Butarque looking to respond after an opening-weekend defeat to Sevilla, where a 97th-minute penalty condemned them to a 2-1 loss despite taking an early lead through Álvaro García. Here’s our Bet Builder pick for Rayo Vallecano v Alaves, which has been placed with Bet365.

Bet Builder • Rayo Vallecano v Alaves
18/1
Thu 20 Aug - 20:00
Bet365 Offer
M. Díaz - 1+ Shots on Target
Player Shots On Target
Reason for tip

Mariano Díaz is positioned as a crucial attacking figure for Alaves, demonstrated by his recent performance where he registered two shots on target. Alaves' attacking style and their ability to create shooting opportunities suggest Díaz will continue to test the opposition goalkeeper. His role within a team averaging eight shots on target per game supports the likelihood of him achieving at least one shot on target in this encounter.

Toni Martínez - 2+ Shots
Player Shots
Reason for tip

Toni Martínez is expected to lead Alaves' offensive efforts, with his previous full-match performance yielding three shots. Alaves' strong start to the season and attacking intent provide a platform for Martínez to take multiple shots. His involvement in the attack and the team's creation of chances make the selection of two or more shots a reasonable expectation for this fixture.

Sivera - 2+ Saves
Goalkeeper Saves
Reason for tip

Alaves goalkeeper Sivera is likely to face significant pressure due to Rayo Vallecano's attacking capabilities and their defensive vulnerabilities shown in recent matches. Sivera's recent performance, where he made two saves in a 3-0 win, indicates his readiness to be tested. Given the anticipated attacking threat from Rayo, Sivera reaching two or more saves appears a plausible outcome.

M. Díaz - Anytime Assist
Player Assists
Reason for tip

Mariano Díaz has shown his creative influence by delivering two assists in limited minutes during his last appearance. His ability to unlock defences and contribute to goal-scoring opportunities aligns with Alaves' offensive approach. Considering his recent impact and the team's intent to press for goals against a defensively vulnerable Rayo side, Díaz providing an assist at any time is a compelling inclusion in this bet builder.

Both Teams To Score YES
Both Teams To Score
Reason for tip

The expectation that both teams will find the net is supported by Alaves' consistent scoring record and Rayo Vallecano's attacking strength, despite some defensive concerns. While Rayo have previously kept clean sheets against Alaves at home, recent defensive changes and injuries suggest vulnerabilities. This balance between attacking promise and defensive frailty underpins the selection of both teams to score in this match.

While Rayo possess a formidable recent home record in this fixture, Alaves enter with a rejuvenated attack. Evaluating the key tactical matchups and individual player outputs points towards a 5-leg Bet Builder priced at 18/1.

Rayo Vallecano v Alaves Bet Builder Tip

M. Díaz – 1+ Shots on Target

Mariano Díaz made an immediate impact in his debut appearance for Alaves, generating significant attacking output in limited minutes to establish himself as a primary threat on target. Coming off the bench for a 33-minute cameo against Getafe, Díaz produced three total shots, directing two of them on target to yield a 67% accuracy rate. His movement in the opposition penalty area produced an expected goals (xG) figure of 0.19 and an expected goals on target (xGOT) value of 0.83, reflecting the genuine quality of his attempts. One of his efforts found the net via a fast break using his right foot, while his overall contribution included three touches inside the opposition box and an aerial duel victory. Over Alaves’ broader 10-match league window, the team has averaged 1.7 goals per game from 13.4 attempts, demonstrating that their frontline creates high-value chances even without holding dominant ball share, as evidenced by their 41.8% average possession.

Díaz’s propensity to test the goalkeeper aligns with Rayo Vallecano’s recent defensive reshuffle. Rayo enter this fixture coping with the summer departures of Pep Chavarría and Nobel Mendy, along with the absence of injured defender Luiz Felipe and uncertainty around Marash Kumbulla. Beñat San José’s backline allowed Sevilla to generate dangerous penalty-box situations in their opening fixture, conceding twice from the spot. This vulnerability in central defensive areas offers Díaz natural channels to hit the target, whether starting alongside Toni Martínez or making another impact appearance off the bench.

The primary counter-evidence lies in the limited sample size of Díaz’s recent output. Having played just 33 minutes of league action this season and failed to score in La Liga across the previous four campaigns, relying on single-match shooting metrics carries an element of variance. Nevertheless, two shots on target from three attempts in under a half of football demonstrates an aggressive shooting mindset that makes one shot on target an attractive focal leg for this match combination.

Toni Martínez – 2+ Shots

Toni Martínez led Alaves’ attack as a starter in their opener against Getafe, completing 90 minutes and accumulating three total attempts. While none of his shots hit the target, his overall physical engagement in the final third was prominent: he registered five touches inside the opposition box, won six total duels, and drew two fouls. His 0.32 xG total from those three attempts underlines his willingness to pull the trigger when opportunities arise.

Rayo Vallecano allowed 14.6 attempts per match over their last 10 league outings, suggesting that opposition central forwards regularly find space to shoot against their defensive setup. The main drawback to Martínez achieving two shots is his lack of shot accuracy in the opening game, where all three efforts failed to test the goalkeeper, alongside his 50% total duel success rate. However, shot volume does not depend on accuracy; playing full 90-minute minutes as a central striker within an attack averaging 13.4 attempts per game provides Martínez with a reliable baseline to reach at least two total shots.

Sivera – 2+ Saves

Antonio Sivera opened his campaign with a clean sheet against Getafe, making two saves to record a 100% save percentage and preventing 0.09 xGOT. Rayo Vallecano consistently generate shot volume, averaging 14.6 attempts and 5.3 shots on target per match across their past 10 league fixtures. In their opener against Sevilla, Rayo put three attempts on target and controlled 51% possession, establishing that they actively test opposing goalkeepers regardless of the final scoreline.

Alaves often concede territorial control to opposition teams, averaging only 41.8% possession over their last 10 matches. This lower possession share naturally invites sustained pressure into Sivera’s defensive third. The chief counterpoint is that Alaves allowed only two shots on target against Getafe, and in several late-season matches last term, Sivera faced minimal save volume when opponents failed to break down Alaves’ defensive shape. Given Rayo’s baseline of 5.3 shots on target per match and their urgency to respond after an opening-day loss, Sivera should reasonably face enough direct testing to record at least two saves.

M. Díaz – Anytime Assist

Mariano Díaz proved remarkably creative during his 33-minute appearance against Getafe, providing two assists and creating two total chances, including one big chance. He registered an expected assists (xA) figure of 0.23, completed his single cross attempt, and recorded two successful dribbles out of three attempts. His ability to turn individual duels into dangerous pass options makes him a dual-threat forward alongside Toni Martínez.

Facing a Rayo Vallecano defensive unit that conceded twice against Sevilla and is adjusting to new personnel combinations after losing Pep Chavarría and Nobel Mendy, Díaz has tangible passing avenues to exploit. The strongest argument against an anytime assist selection is the high natural variance of assist markets for central forwards, combined with the fact that two assists in 33 minutes represents an exceptional short-term spike. However, despite regression expected over a full season, his immediate willingness to set up teammates in the penalty area adds strong value to the overall combination.

Both Teams To Score YES

Both sides possess established scoring trends heading into this fixture. Alaves scored three goals in their opening match and have averaged 1.7 goals per game over their previous 10 league outings. Rayo Vallecano opened their scoring tally within four minutes against Sevilla through Álvaro García and average 1.4 goals per match across their own 10-game sample, supported by 14.6 attempts per game and 5.3 shots on target.

Rayo’s current defensive vulnerabilities—evidenced by conceding two penalties in their opening fixture and missing key defenders like Luiz Felipe—increase the likelihood of Alaves scoring. Conversely, Alaves conceded 56 goals in La Liga last season and won just four of 15 away matches, indicating persistent defensive gaps on the road. The main counterpoint is historical precedent: Rayo have won their last four home league meetings against Alaves without conceding a single goal. Nevertheless, recent scoring form and current defensive adjustments indicate both attacks have sufficient potency to break through during 90 minutes.
