Form and standing: two different trajectories
The round-11 derby at San Mamés (kick-off 20:00 UTC on 1 November) pairs two sides moving in different directions. Real Sociedad sit fifth after ten league games, with six wins, one draw and three defeats for 19 points. Their goal tally is 19 for and 18 against, so they are winning matches that stay open. Their last four league results are all wins: 3-2 against Deportivo La Coruña, 5-2 at Málaga, and 2-1 against Levante, with a 3-2 win at Valencia before that. The one blemish in the run is a 3-0 home loss to Atlético Madrid on 13 September.
Athletic are seventh on 12 points from nine games (three wins, three draws, three defeats) with 12 goals scored and nine conceded. Their recent run is patchy: draws against Elche, Alavés and Valencia, a 3-1 defeat at Levante on 21 October, and then a 4-0 home win over Getafe on 25 October. That Getafe result is their biggest of the campaign and shows how much the attack can produce when it clicks, but it followed a stretch where goals were hard to find.
Athletic Club: Terzić’s side and the injury list
Edin Terzić’s team have been hard to beat at home without being dominant. The Alavés and Elche games at San Mamés both finished level, and Athletic’s recorded ratings sit just below average on both sides of the ball (attack 0.97, defence 0.97 over a 20-match sample). Those numbers help explain why the models see a tight game rather than a comfortable home win.
Availability is the main concern. A [1] preview published on 25 October listed Aymeric Laporte as out through suspension and Gorka Guruzeta as still injured. That article was written for the Getafe game, so the Laporte situation should be checked against the final team news. If he is absent, the defence loses a player who, according to [2], was a cornerstone of a Spain back line that conceded just one goal in eight World Cup matches. Several of the models cite his absence as the main reason to keep the margin narrow.
Real Sociedad: Matarazzo’s momentum and gaps of their own
Pellegrino Matarazzo’s side arrive as the form team. Their recorded ratings (attack 1.27, defence 1.23) are clearly above Athletic’s, and the five-goal win at Málaga shows how freely they can score. [3] describes Matarazzo’s first nine months as positive, with a title, European qualification and a fifth-place league position. In midfield, [4] reported that Luka Sučić was in Matarazzo’s starting lineup and contributed in attack and defence after the club sold Brais Méndez in the summer.
The visitors do have problems. They have conceded 18 goals in ten games and allowed at least two in each of their last four wins, which is why the matches have been so open. [5] reported Jon Aramburu as out injured, and [6] reported that Luken Beitia suffered a left ankle sprain in training. Both are absences to watch when the lineup is confirmed.
Predictions: a narrow home edge, with the draw live
The Poisson baseline, built from recorded results, projects 1.91 expected goals for Athletic and 1.44 for Real Sociedad. It gives the hosts a 48.8% chance of winning, with 22.2% for a draw and 29.0% for an away win. Its single most likely scoreline is 1-1, but the most likely score within a home win is 2-1. The baseline puts the chance of both teams scoring at 64.9% and of over 2.5 goals at 65.0%.
The five AI models all land on a home win. Claude Keeper, Kimi Cool and DeepThinker each pick 1-0, with home probabilities of 40-42% and a draw at 27-30%. Gemini Thunder and GPT Striker go for 2-1, with GPT Striker the most confident at 45% for the home side. Gemini Thunder is the least convinced, at 38% home and 34% away.
The head-to-head offers little separation. Real Sociedad won 3-2 on 1 November 2025, and the return fixture on 1 February 2026 finished 1-1. The models lean on home advantage and Athletic’s 4-0 win last time out, while the table and ratings favour the visitors. With both defences leaking and a possible Laporte absence, the baseline’s high both-teams-to-score figure deserves as much attention as the models’ tighter 1-0 scorelines.
