Athletic Club vs Celta Vigo: High-Stakes La Liga Clash

San Mamés hosts a high‑stakes late‑season clash on 17 May 2026 as Athletic Club welcome Celta Vigo in La Liga’s Round 37. With Celta sitting 6th on 50 points and currently in a Europa League league‑phase spot, and Athletic 9th on 44 points, this is a fixture that could reshape the European race and the final top‑half picture.

Context: contrasting trajectories, similar records

In the league, the table tells a nuanced story. Both sides have identical overall win records (13 wins each from 36 games), but Celta’s extra draws (11 vs Athletic’s 5) and superior goal difference (+4 vs Athletic’s -13) have pushed them into 6th.

Athletic’s campaign has been volatile. Their all‑phase form string – “WWWLLDLWDLLWLWLWLLDLLDWWWDLLWLLWLWLL” – underlines the streakiness that has left them in mid‑table. Their last five league games read “LLWLW”, a run that mixes damaging defeats with occasional responses.

Celta, by contrast, have been more resilient if inconsistent, with a season‑long form line of “LDDDDDLDDWWLWLWWDWWWLDLDWWLDLWLLLWWL”. Their last five (“LWWLL”) encapsulate a side that can string wins together but is still prone to sharp dips.

Home and away splits sharpen the picture. Athletic are much stronger at San Mamés: 9 wins, 2 draws and 7 defeats from 18 home matches, scoring 21 and conceding 20. Celta have quietly become one of La Liga’s better away sides: 8 wins, 6 draws and just 4 losses on the road, with 23 scored and 19 conceded. That away solidity sets up a genuine clash of strengths.

Tactical landscape: systems, structure and where the game is won

Across all phases, Athletic have leaned heavily on a 4‑2‑3‑1 (35 uses) with an occasional 4‑1‑4‑1. That points to a double pivot shielding a back four, with a central creator and wide forwards asked to support a lone striker. The structure is designed for controlled pressing and quick vertical attacks, but the numbers suggest imbalance: 40 goals scored (1.1 per game) against 53 conceded (1.5 per game). At home, they average 1.2 goals for and 1.1 against, so San Mamés does tighten them up slightly.

Celta’s tactical identity has been more flexible but consistently back‑three based: 3‑4‑3 (26 times) and 3‑4‑2‑1 (8 times) dominate, with only occasional back‑four experiments (one game each in 4‑3‑3 and 4‑4‑2). The three‑centre‑back shape, with wing‑backs high, is designed to give width and counter‑attacking punch while keeping a solid central block. It has worked reasonably well: 51 goals for (1.4 per game) and 47 against (1.3 per game), with an especially tidy away defence (19 conceded in 18).

In structural terms, this is likely to be Athletic’s 4‑2‑3‑1 trying to press and overload wide areas against Celta’s 3‑4‑3 lanes. Athletic’s double pivot will need to track Celta’s inside forwards and late runs from midfield, while their full‑backs face a demanding night against Celta’s wing‑backs and wingers.

Set‑pieces and discipline could also be decisive. Athletic’s yellow‑card profile spikes between minutes 46‑75, with 31 yellows in that middle third of games. Celta similarly pick up many cards between 46‑90 (28 yellows). With both sides prone to late bookings, control of transitions in the second half will matter.

Key absences and selection headaches

Athletic arrive with significant personnel issues. Three important players are listed as “Missing Fixture”:

• O. Sancet – muscle injury
• D. Vivian – ankle injury
• N. Williams – injury

On top of that, Y. Berchiche (leg injury) and B. Prados Diaz (knee injury) are both “Questionable”.

Losing N. Williams strips Athletic of a major wide threat and ball‑carrying outlet, while Sancet’s absence removes creativity between the lines. Vivian’s injury weakens central defence, and if Berchiche does not make it, Athletic could be forced into rotation or a more conservative full‑back approach. The net effect is likely to be a less explosive, more workmanlike attacking unit.

Celta also have issues, but arguably with slightly less structural damage:

• M. Roman – foot injury (Missing Fixture)
• C. Starfelt – back injury (Missing Fixture)
• I. Moriba – knee injury (Questionable)
• M. Vecino – muscle injury (Questionable)

Starfelt’s absence is notable in a three‑centre‑back system, potentially forcing a reshuffle or a less experienced defender into a key role. If both Moriba and Vecino are unavailable, Celta’s central midfield depth is tested, and they may have to lean on more attack‑minded or less experienced options in the double pivot.

Celta’s spearhead: Borja Iglesias

The standout individual in the data is Celta’s centre‑forward Borja Iglesias. Across all phases of the 2025 La Liga season, he has:

• 33 appearances (19 starts), 1,770 minutes
• 14 goals and 2 assists
• 38 shots, 26 on target
• 17 key passes
• 4 penalties scored from 4, no misses

His scoring rate – roughly a goal every 126 minutes – is elite for a side outside the top four, and his penalty record is flawless in the data provided. Physically strong (187 cm, 86 kg) and active in duels (168 contested, 64 won), he is central to Celta’s ability to turn territorial parity into goals.

Against an Athletic defence missing Vivian and potentially reshuffled at left‑back, Iglesias’ movement between centre‑backs and his ability to pin the line could be decisive. Celta’s wing‑backs and attacking midfielders will look to feed him early crosses and cut‑backs, especially given Athletic’s vulnerability when the game stretches.

Head‑to‑head: finely balanced recent history

The last five competitive meetings in La Liga show a narrow edge for Athletic but with both sides winning twice:

1. 14 December 2025, Estadio Abanca Balaídos: Celta Vigo 2-0 Athletic Club – Celta win
2. 19 January 2025, Estadio Abanca-Balaídos: Celta Vigo 1-2 Athletic Club – Athletic win
3. 22 September 2024, San Mamés Barria: Athletic Club 3-1 Celta Vigo – Athletic win
4. 15 May 2024, Estadio Abanca-Balaídos: Celta Vigo 2-1 Athletic Club – Celta win
5. 10 November 2023, San Mamés Barria: Athletic Club 4-3 Celta Vigo – Athletic win

Across these five, Athletic have 3 wins, Celta 2, with no draws. Notably, the two matches at San Mamés in this sample both ended in Athletic victories (3-1 and 4-3), suggesting that the Bilbao crowd has often tilted this fixture in the hosts’ favour, even in high‑scoring, chaotic contests.

Fine margins: goals, clean sheets and penalty edges

Across all phases this season, Athletic have kept 6 clean sheets (4 at home), failing to score 13 times. Celta have 9 clean sheets (6 away), failing to score just 6 times. That combination – Celta’s strong away defence and reliable scoring – is a major factor.

Both sides have perfect team‑level penalty records in the data: Athletic 5 scored from 5; Celta 8 from 8. With Borja Iglesias personally 4/4, any spot‑kick could be a crucial advantage, especially in a tight, late‑season contest.

The verdict

Athletic’s home strength, the atmosphere at San Mamés and a favourable recent home record against Celta suggest they will not be overrun, even with key attacking absences. However, Celta’s superior league position, more balanced goal difference, excellent away record (8-6-4, 23-19) and the presence of an in‑form finisher in Borja Iglesias give the visitors a slight edge.

Expect Athletic to try to impose intensity and direct play, but without N. Williams and O. Sancet they may lack the cutting edge to consistently unpick Celta’s back three. Celta, disciplined in their 3‑4‑3 structure, should find moments in transition and through set‑pieces.

A tight, tactical game is likely. On the balance of the data, a draw or a narrow Celta win feels the most logical outcome, with Celta marginally better placed to exploit the small margins that usually decide late‑season fixtures of this type.
