Athletic Club vs Osasuna: Mid-Table Clash in La Liga
San Mamés stages a mid-table Basque–Navarre clash in April 2026 as Athletic Club host Osasuna in La Liga’s Regular Season round 33. Only one point separates the sides in the league: Osasuna are 9th on 39 points, Athletic 11th on 38. With six games left, both are close enough to the European conversation to keep their season alive, but also near enough to the pack below that a bad week could drag them into a nervous run-in. The stakes are clear: a win here could be the launchpad for a late surge up the table.
Context and form
Across all phases this season, Athletic’s campaign has been streaky. Their league form line reads “LLWLL”, underlining a recent slump: three defeats in their last four, and 15 losses from 31 matches overall. Yet at San Mamés they remain awkward opponents: 8 wins from 16 home games, with a positive goals record (20 scored, 19 conceded).
Osasuna arrive marginally better placed but equally inconsistent. Their overall record (10 wins, 9 draws, 12 defeats) is underpinned by a strong home campaign and a very fragile away one. Jagoba Arrasate’s side have taken just 2 wins from 16 away matches, losing 10 and scoring only 11 goals on the road. Their current league form “DDWLD” points to resilience more than brilliance – three draws in five, but just one win.
Goal difference tells its own story. Osasuna sit at -1 (37 scored, 38 conceded), suggesting a broadly balanced side. Athletic’s -12 (33 for, 45 against) reflects heavier defeats and a more porous back line, especially away – though at home their goals against average (1.2 per game) is respectable.
Tactical outlook: styles and key trends
Athletic have been remarkably stable tactically. Across all phases they have lined up in a 4-2-3-1 in 30 of 31 league matches, only once deviating into a 4-1-4-1. That continuity should help them control the rhythm at San Mamés: a double pivot to shield the defence, full-backs encouraged to push, and three advanced midfielders tasked with linking to the lone striker.
The numbers suggest a side that often needs to work hard for goals. Athletic average 1.1 goals per game overall (1.3 at home), and they have failed to score in 11 of their 31 matches. When they do click, they can be explosive – their biggest home win is 4-2 – but those days have been rare. Defensive vulnerability is a concern: 45 goals conceded at 1.5 per game, and only 5 clean sheets all season.
Osasuna are more flexible structurally. Arrasate has used 4-2-3-1 most often (16 times), but has also switched into back-three systems (3-4-3, 3-4-2-1, 3-5-2, 3-1-4-2) and even 5-4-1. That tactical versatility is likely to show in Bilbao: an away 3- or 5-man back line to crowd the box, with transitions geared towards their focal point in attack.
Their offensive profile is similar in volume to Athletic’s (1.2 goals per game), but the home/away split is stark: 26 of 37 goals have come at El Sadar. Away, they average just 0.7 goals per match and have failed to score 10 times on their travels. That suggests Osasuna will lean heavily on structure, set pieces and the individual quality of their main striker rather than expansive play.
Defensively, Osasuna are marginally tighter than Athletic, conceding 38 (1.2 per game). They have kept 7 clean sheets overall, including 2 away, but their 21 goals conceded on the road underline that they can be opened up if the home side sustain pressure.
Discipline could be a sub-plot. Both teams rack up yellow cards, but Osasuna’s red-card profile is notable: multiple dismissals late in games across all phases. In a tight contest, composure in the final quarter could be decisive.
Head-to-head: recent edge with a twist
Looking strictly at competitive meetings (excluding the 2024 club friendly), the last four encounters between these sides are finely poised:
- In January 2026 at El Sadar, they drew 1-1 in La Liga.
- In March 2025 at San Mamés, a league game finished 0-0.
- In January 2025 in the Copa del Rey 1/8 final, Osasuna won 3-2 away at San Mamés.
- In December 2024 at El Sadar, Athletic won 2-1 in La Liga.
That gives, over the last four competitive games: 1 win for Athletic, 1 win for Osasuna, and 2 draws.
The pattern is interesting: both have already won away in this fixture in the last two seasons, and San Mamés has hosted a goalless stalemate and a five-goal cup thriller. There is no clear psychological dominance, but Osasuna’s 3-2 Copa triumph in Bilbao in January 2025 will remind the visitors they can hurt Athletic on this pitch.
Team news and selection implications
Athletic are without B. Prados Diaz, ruled out with a knee injury. In a side that relies heavily on its double pivot, his absence could reduce options for rotation and ball-winning in midfield. However, the core 4-2-3-1 structure is unlikely to change.
Osasuna’s issues are more severe. I. Benito is sidelined with a knee injury, but the bigger blows are at the back: A. Catena is suspended due to yellow-card accumulation, and A. Osambela is out with a red-card suspension. For a team that already struggles away, losing two defensive options disrupts continuity and may force a reshuffle in both system and personnel. It strengthens the case for a more conservative shape, possibly with an extra centre-back to cover for the absentees.
Key player: Ante Budimir
The standout individual in this fixture is Osasuna’s centre-forward Ante Budimir. Across all phases in La Liga 2025, he has 16 goals in 30 appearances, a return that places him among the league’s top scorers. He has generated those numbers from 70 shots (32 on target), underlining his volume and willingness to take responsibility.
Budimir is more than a finisher: 339 passes with 12 key passes point to his role as a reference point who can link play, while 316 duels and 151 won highlight his aerial and physical presence. In a match where Osasuna may see less of the ball, his ability to hold up long passes, win fouls (32 drawn) and bring midfield runners into play will be central to their attacking plan.
From the spot he is dangerous but not flawless: 6 penalties scored and 1 missed. If a penalty arrives in Bilbao, his record suggests a strong but not perfect weapon.
For Athletic, the absence of detailed individual attacking stats in the data means the threat is more collective. Their best home performances – including that 4-2 win which stands as their biggest home victory across all phases – have come when the wide players and attacking midfielders combine aggressively around the box. With Osasuna’s defensive suspensions, this is a game where Athletic’s second-line runners could find space between full-back and centre-back.
Tactical battle lines
Expect Athletic to dominate territory and possession, especially early on. Their 4-2-3-1 should push Osasuna back, with full-backs overlapping and the double pivot tasked with recycling second balls and preventing counters. The key for the hosts will be turning pressure into clear chances – something they have not always managed, given those 11 matches without scoring.
Osasuna, by contrast, are likely to sit in a mid-to-low block, compressing central areas and funnelling Athletic wide. On the break, they will look early for Budimir, either in the air or into the channels, supported by quick wide players. Set pieces – corners and free-kicks – will be vital, both as a route to goal and as moments to slow the game down and relieve pressure.
Given Osasuna’s away scoring issues and Athletic’s relatively solid home defensive numbers, an open, end-to-end contest feels unlikely unless an early goal breaks the pattern.
The verdict
The data points to a tight, attritional game at San Mamés. Athletic’s strong home record (8 wins in 16) meets Osasuna’s poor away return (2 wins in 16, 10 defeats), and the visitors are further weakened by suspensions in defence. Osasuna do have the game’s most reliable scorer in Budimir, and recent head-to-heads show they are capable of getting results in Bilbao, but their chronic away goal shortage is hard to ignore.
Athletic’s inconsistency and recent “LLWLL” form temper expectations of a dominant display, yet the context – home advantage, a cleaner bill of health, and Osasuna’s back-line absences – tilts the balance their way.
On the balance of narrative, tactics and numbers, a narrow Athletic win in a low-scoring match looks the most logical outcome, with the hosts edging a cautious contest decided by fine margins rather than sustained attacking fluency.
