Bilbao at Alaves: Both Teams to Score

Athletic Bilbao demonstrates offensive strength but lacks full defensive vulnerability. In their last five La Liga matches, Athletic Bilbao achieved an average Expected Goals (xG) of 1.6 ^[1], ^[2], indicating strong offensive potency as this figure is above the 1.1 threshold. Their defensive metrics, however, show an average Expected Goals Against (xGA) of 1.1 over the same period ^[1]. While this is a notable figure, it does not strictly meet the defined condition of being above 1.1 for defensive vulnerability.

Assessing Alavés' recent form is currently hindered by data limitations. The available research, specifically the 2024-2025 Alavés Stats from fbref.com ^[3], provides general season statistics. However, these sources do not offer the necessary specific Expected Goals (xG) and Expected Goals Against (xGA) averages for Alavés' last five respective La Liga matches, nor do they allow for their immediate calculation. Therefore, a comprehensive evaluation of Alavés' offensive potency and defensive vulnerability for this specific period cannot be conducted with the information at hand.

Consequently, confirming simultaneous potency and vulnerability for both teams is not possible. Athletic Bilbao exhibits offensive potency with an xG of 1.6 (greater than 1.1), but their xGA of 1.1 does not strictly meet the criteria for defensive vulnerability (not greater than 1.1). Due to the absence of specific 'last five match' xG and xGA averages for Alavés in the provided research, a conclusive assessment of whether both teams simultaneously meet the specified offensive potency and defensive vulnerability conditions cannot be made.

Deportivo Alavés's top scorer, Samu Omorodion, is predicted to start. Omorodion has netted 9 goals for the 2025-26 season, making him the team's leading goalscorer according to several sources ^[1]. He is expected to be included in the starting lineup for the upcoming match against Athletic Club ^[2].

Athletic Club faces a defensive change due to a key injury. Daniel Vivian is projected to start in the central defense ^[2]. However, Yeray Álvarez will be unavailable for the match, as he is currently sidelined with a thigh injury ^[2]. The anticipated starting central defensive pairing for Athletic Club is Daniel Vivian alongside Aitor Paredes ^[2].

Only 20% of recent Alavés vs. Athletic matches had both teams score. Out of the last five La Liga head-to-head encounters between Alavés and Athletic Bilbao at Alavés's home stadium, Mendizorrotza, only one match saw both teams find the net. This sole instance occurred on January 05, 2019, in a 1-2 result ^[1]. Consequently, both teams scored in just 20% of these specific encounters. The scores from these five matches include Alavés 0-2 Athletic Club (September 22, 2023), Alavés 0-0 Athletic Club (April 10, 2022), Alavés 1-0 Athletic Club (January 23, 2021), Alavés 0-2 Athletic Club (October 27, 2019), and Alavés 1-2 Athletic Club (January 05, 2019) ^[1].

Matches at Mendizorrotza typically feature cautious and defensive tactics. The prevailing trend in these fixtures indicates a cautious and defensive tactical approach from both teams, consistently leading to low-scoring affairs. Four of the five reviewed matches featured at least one team failing to score, which included two clean sheets for Athletic Bilbao, one clean sheet for Alavés, and a goalless draw ^[1]. This pattern underscores a prioritization of defensive solidity and limiting opponent opportunities over expansive attacking play.

The most recent match exemplifies this defensive-first approach and outcome. For instance, in the most recent home fixture for Alavés on September 22, 2023, Alavés struggled to create significant chances, allowing Athletic Club to control the game and secure a 0-2 victory ^[2]. The consistent occurrence of tight margins and defensive discipline highlights the tactical mindset often employed by both teams when they meet at Mendizorrotza.

Alavés faces minimal motivational stakes, being safe from relegation. Currently in 10th place with 40 points, Alavés holds a comfortable 9-point lead over the relegation zone, which begins with 18th-place Elche at 31 points ^[1]. As 40 points is generally considered the threshold for La Liga survival, Alavés is virtually assured of safety. Furthermore, European contention is beyond their reach, as they are 13 points behind 6th-place Athletic Bilbao, who hold a European qualification spot with 53 points ^[1]. Consequently, Alavés is not in a 'must-win' situation for either relegation safety or European qualification, suggesting that a draw would be a satisfactory outcome for them.

Athletic Bilbao holds significant stakes for European qualification. Occupying 6th place with 53 points, Athletic Bilbao currently secures a UEFA Europa Conference League spot ^[1]. A victory would be highly advantageous, offering the chance to climb into a more prestigious UEFA Europa League position, as they are only 1 point behind 5th-place Real Betis (54 points) ^[1]. Simultaneously, they must protect their current standing from 7th-place Real Sociedad, who trail by 5 points with 48 points ^[1]. A win would thus not only provide an opportunity to secure a better European competition but also extend their buffer over Real Sociedad, substantially solidifying their European aspirations and necessitating an aggressive, attacking posture.
