Real Betis1-0Real Sociedad

Round two of the 2026-27 La Liga season takes Real Betis and Real Sociedad to the Estadio de La Cartuja. The new campaign has yet to produce a meaningful table, so the statistical picture below is built entirely from the 2025-26 season.

Betis finished fifth with 60 points and a goal difference of +11, while Sociedad ended tenth on 46 points at -2. Both sides scored 59 goals, but the defensive gap was large: Betis conceded 48, Sociedad 61. The model gives Betis a 54.7% chance of winning, with a projected scoreline of 2-1.

Betis' 2025-26 season was anchored by a strong home record. Over their last 20 home matches they won 11, drew six and lost three, a 55% win rate, while averaging 1.9 goals scored and 0.95 conceded per game. That compared favourably with their overall season figures of 1.55 scored and 1.26 conceded per match.

Their most recent five league results on record are W-W-W-L-W, with an average of two goals scored and one conceded per game. They last played on 29 July and arrive here after a 23-day rest period.

Sociedad's away form was a persistent weakness in 2025-26. Across their last 20 away matches, they won only four, drew eight and lost eight, a 20% win rate, averaging 1.3 goals scored and 1.6 conceded.

Their overall numbers were mixed: sixth-ranked attack but 19th-ranked defence. Their last five league results on record read W-D-L-D-D (most recent first), averaging 2.2 goals scored and 2 conceded per game. They last played on 28 July and come in with 24 days of rest.

The head-to-head record spans four meetings. Betis have two wins, one draw and one loss; Sociedad have one win, one draw and two losses. The aggregate score is 8-5 in Betis' favour.

Goals have been frequent: 13 in four games, an average of 3.25 per match, and only one of those meetings finished with two or fewer total goals. The most recent meeting on 9 May 2026 saw Real Sociedad host Real Betis and end 2-2. The prior three meetings: Real Betis won 3-1 and 3-0 at home, and Real Sociedad won 2-0 at home.

The home and away splits tell a consistent story. Betis' home win rate of 55% over their last 20 home games is the clear counterpart to Sociedad's 20% away win rate over their last 20 road games.

Betis have scored at 1.9 per game at home versus 1.55 overall, while Sociedad have conceded 1.6 per game away versus 1.61 overall. The model's expected-goal projection for this match is 2.13 for Betis and 1.37 for Sociedad.

Both teams come in with long rest periods: Betis last played on 29 July, Sociedad on 28 July, giving them 23 and 24 days off respectively.

Schedule strength offers no clear advantage: Betis faced an average opponent rank of 10.7 across their three most recent fixtures, Sociedad an average of 11.0 across four. Both figures indicate a moderately difficult run-in, but not an extreme one.

The widest gap in the underlying data is defensive: Betis ranked seventh in the league for goals conceded, Sociedad 19th. That gap is what the model leans on most heavily, but the data is from the previous season, and the new campaign's table is too small to confirm either side has carried that form forward.

The Poisson model rates this as a high-confidence projection. Betis are given a 54.7% win probability, a draw 20.8%, and Sociedad 24.5%. The most likely outcome is a Betis win, with the most probable exact scoreline 2-1 at 9.4%. The other most likely exact scorelines are 1-1 (8.8%) and 2-0 (6.8%).

The model expects roughly 3.5 total goals. It puts an 86.4% probability on at least two goals being scored, 67.9% on at least three, and 46.3% on at least four. The chance that both sides score at least once is 65.8%.

Looking at the winning margin, the single largest category is a Betis win by two or more goals, at 33%. A Betis win by exactly one goal is 21.7%, the draw 20.8%, a Sociedad win by one 14%, and a Sociedad win by two or more 10.5%. In other words, the model sees a comfortable home win as the most common specific outcome, but it is far from certain.

The data points to a home win. Betis' home strength, Sociedad's away struggles, and the defensive contrast all align with the model's 54.7% likelihood for Betis. The projected 2-1 scoreline fits with the high-scoring head-to-head pattern, where three of the four meetings produced at least three goals.

However, the model also assigns a one-in-five chance to the draw and about one-in-four to an away win. Sociedad's attack is ranked sixth, so they are not toothless. The biggest caveat is the source of the numbers: with no reliable current-season table, the entire projection rests on 2025-26 performance. If the true balance of strength has shifted since then, the model's confidence could be misplaced.
