Athletic Club vs Celta Vigo: Late-Season La Liga Clash Preview

San Mamés stages a compelling late-season La Liga clash on 17 May 2026 as Athletic Club host Celta Vigo in Round 37. With just two games left, both sides are jostling for European positioning and pride: Celta arrive in 6th on 50 points, sitting in the Europa League places, while Athletic are 9th with 44 points and looking to salvage a mixed campaign.

Context and stakes

In the league, Celta’s 6th place is underpinned by a positive goal difference (+4) and a solid all-round record: 13 wins, 11 draws, 12 defeats, with 51 goals scored and 47 conceded. Athletic, three places lower, have the same number of wins (13) but far fewer draws (5) and more losses (18), leaving them with a negative goal difference (-13) and a more volatile profile.

At home, Athletic have been relatively strong: 9 wins, 2 draws and 7 defeats from 18 at San Mamés, scoring 21 and conceding 20. Celta, though, have been one of La Liga’s better travellers, with 8 away wins, 6 draws and only 4 defeats, scoring 23 and allowing just 19. That away resilience, set against Athletic’s patchy form, gives this fixture real tactical intrigue.

Form and tactical identities

Across all phases this season, Athletic’s form line (“WWWLLDLWDLLWLWLWLLDLLDWWWDLLWLLWLWLL”) tells a story of streaks and sharp swings. Their league snapshot form of “LLWLW” underlines that inconsistency: three defeats in the last five, punctuated by two wins. Goals data reinforces the picture of a side that can be dangerous but fragile: 40 scored and 53 conceded in the league, with averages of 1.1 scored and 1.5 conceded per game. At home, they average 1.2 for and 1.1 against, so San Mamés has not been the fortress of previous years but remains competitive.

Tactically, Athletic are heavily defined by their 4-2-3-1: they have lined up that way in 35 of 36 league matches, with a lone outing in 4-1-4-1. That double-pivot base is meant to protect a back line that has still leaked 53 goals, suggesting structural issues in defensive transitions and perhaps individual errors. They have managed 6 clean sheets across all venues (4 at home), but they have also failed to score 13 times, including 5 at San Mamés, indicating that when the attacking patterns stall, they can become blunt quickly.

Celta, by contrast, have embraced a back-three system. Their most-used setup is 3-4-3 (26 matches), complemented by 3-4-2-1 (8 matches). Only occasionally have they shifted to a back four (one game each in 4-3-3 and 4-4-2). This stable three-at-the-back identity has underpinned a solid defensive record away from Vigo (19 conceded in 18) and a balanced attack averaging 1.3 goals per away game. Across all phases they have 9 clean sheets (6 away) and have failed to score just 6 times in total, which is a strong platform for an away side.

Their broader form string (“LDDDDDLDDWWLWLWWDWWWLDLDWWLDLWLLLWWL”) shows extended runs of draws and some recent clusters of wins and losses, but the current snapshot “LWWLL” hints at volatility: two wins followed by two defeats after a victory. They are not cruising into Bilbao, but their underlying away metrics remain impressive.

Key players and attacking threats

Celta’s standout attacking figure is Borja Iglesias. The 32-year-old forward has 14 league goals and 2 assists in 33 appearances, with 26 of his 38 shots on target – a high level of efficiency. He has also scored 4 penalties without a miss. His minutes (1,770) and 19 starts underline his importance as the focal point of Celta’s front line, particularly in a 3-4-3 where he can occupy centre-backs and open space for wide forwards and wing-backs.

His physical profile (187 cm, 86 kg) fits perfectly with Celta’s crossing and transition play from wide areas in a back-three system. The fact he has drawn 28 fouls and committed 33 indicates he is deeply involved in duels (168 total, 64 won), constantly battling in central zones. Against an Athletic defence missing a key centre-back, that could be decisive.

Athletic’s individual attacking data is not provided in the same depth here, but team-level numbers show they have scored only 21 times at home in 18 matches. Their biggest home win is 4-2, and their biggest home defeat is 0-3, which underlines the swing between their best and worst days. With 13 total failures to score, they can be shut down if the opposition control central zones and deny them rhythm in the final third.

One potential bright spot for Athletic is their record from the spot: 5 penalties, all 5 scored, with no misses. That gives them a reliable fallback in tight games, especially at home, though there is no player-level breakdown here to highlight a specific taker.

Absences and squad news

Athletic are hit hard by absences. Three important players are listed as “Missing Fixture”:

Oihan Sancet – Muscle Injury
Dani Vivian – Ankle Injury
Nico Williams – Injury

Sancet’s absence removes a key creative and linking presence between midfield and attack in the 4-2-3-1, potentially forcing a more functional No.10 or a deeper midfield line. Vivian’s injury weakens the centre-back options in a side already conceding 53 goals, and against a physical striker like Borja Iglesias that is a significant concern. Nico Williams’ injury robs Athletic of one of their most dynamic wide threats, reducing their capacity to stretch Celta’s back three and attack in behind.

Two more players are listed as “Questionable”:

Yuri Berchiche – Leg Injury
Beñat Prados Diaz – Knee Injury

If Berchiche is unavailable or below full fitness, Athletic lose an experienced, aggressive left-back who is crucial for both width and defensive balance. Prados Diaz’s status affects midfield rotation and depth.

Celta’s injury list is shorter but still notable:

Missing Fixture:
Miguel Román – Foot Injury
Carl Starfelt – Back Injury

Starfelt’s absence removes an experienced central defender from that three-man back line, which could force a reshuffle or bring in a less tested option. Román’s injury further trims depth.

Questionable for Celta:

Ilaix Moriba – Knee Injury
Matías Vecino – Muscle Injury

Both are central midfielders. If either or both are unavailable, Celta’s double pivot or central trio will be lighter, potentially affecting their ability to control possession and protect the back three, especially against Athletic’s central overloads in a 4-2-3-1.

Head-to-head: recent history

The last five competitive meetings in La Liga show a finely balanced rivalry:

14 December 2025, Estadio Abanca Balaídos: Celta Vigo 2-0 Athletic Club – Celta win.
19 January 2025, Estadio Abanca-Balaídos: Celta Vigo 1-2 Athletic Club – Athletic win.
22 September 2024, San Mamés Barria: Athletic Club 3-1 Celta Vigo – Athletic win.
15 May 2024, Estadio Abanca-Balaídos: Celta Vigo 2-1 Athletic Club – Celta win.
10 November 2023, San Mamés Barria: Athletic Club 4-3 Celta Vigo – Athletic win.

Across these five, Athletic have 3 wins, Celta have 2, and there have been 0 draws. Notably, the home side has won all three fixtures in Bilbao, while Celta’s two victories have come in Vigo. That pattern reinforces the importance of home advantage at San Mamés, even against a strong away team like Celta.

Tactical battle zones

Given the data, several key tactical themes emerge:

Athletic’s 4-2-3-1 vs Celta’s 3-4-3: Athletic’s two holding midfielders will be vital in screening the back four against Borja Iglesias and Celta’s wide forwards. In possession, the No.10 zone becomes crucial to exploit spaces between Celta’s midfield line and back three. Without Sancet, that role may be less creative, potentially pushing Athletic towards more wing-based attacks and crosses.
Wide areas and wing-backs: Celta’s 3-4-3 relies heavily on wing-backs to provide width. If Athletic’s full-backs, especially a possibly less-than-fully-fit Berchiche, cannot pin them back, Celta can overload the flanks and deliver quality into Iglesias. Conversely, if Athletic can isolate Celta’s wide defenders 1v1 despite Nico Williams’ absence, they can exploit the channels behind the wing-backs.
Set pieces and discipline: Both sides pick up a high volume of yellow cards, particularly after half-time. Athletic’s yellow-card distribution spikes between 46-75 minutes; Celta’s is highest between 46-60 and 76-90. In a tight game, a late card or dismissal could tilt the balance, especially with Celta already missing Starfelt and Athletic thin at centre-back.
Defensive solidity vs attacking volatility: Celta’s 9 clean sheets (6 away) and relatively low away goals against (19) contrast with Athletic’s 53 goals conceded overall. If Celta can impose their away structure, they are well equipped to frustrate an Athletic attack missing key pieces and then strike through Iglesias and transitions.

The verdict

All indicators point to a finely balanced contest. Athletic’s strong home record and recent dominance over Celta at San Mamés weigh on one side of the scale; Celta’s superior league position, better goal difference, and excellent away record weigh on the other.

Injuries may be the decisive factor. Athletic are without Sancet, Vivian and Nico Williams, three players central to their spine and attacking edge, and have doubts over Berchiche and Prados Diaz. Celta, while missing Starfelt and Román and potentially Moriba and Vecino, still retain their main attacking weapon in Borja Iglesias and the core of their 3-4-3 structure.

Expect Athletic to lean on intensity, home backing and set pieces, while Celta look to control space, exploit wide channels and feed Iglesias early. A tight, tactical game feels likely, with Celta marginally better placed to avoid defeat, but Athletic’s home trend in this head-to-head means a draw or narrow home win are both plausible outcomes.
