Real Madrid4-1Real Sociedad

This is the season opener for both sides in La Liga. The data, drawn from the 2025-2026 campaign, shows Real Madrid finishing second with 86 points while Real Sociedad were 10th with 46. The model gives Real Madrid a 74.4% win probability, the clearest signal in this fixture.

Real Madrid were the league's second-best attack and best defence last season, averaging 2.03 goals scored and 0.92 conceded per game. Their last five outings produced four wins and a draw, with an average of 2.4 goals scored and 1 conceded. Ten days' rest separates them from their latest match.

Real Sociedad averaged 1.55 goals scored but 1.61 conceded, the league's second-worst defensive figure. Their recent five-match form is L-L-L-L-W, with four defeats and one win, conceding an average of two goals per game. They played five days ago against a top-five-ranked opponent.

Real Madrid have won all four recorded meetings, scoring 10 and conceding 2. Half of those matches finished with two or fewer total goals, though the most recent produced a 4-1 scoreline. The sample is small but the pattern is one-sided.

At home in their last 20 matches, Real Madrid have won 70%, scoring 2.5 goals per game. Real Sociedad's away record over the same sample is a 20% win rate, with 1.3 goals scored and 1.65 conceded per game.

As a season opener, both sides are on equal rest footing, but Real Madrid's defensive excellence and Real Sociedad's defensive frailty stand out from last season's numbers. The schedule-strength marker gives Real Sociedad a tougher recent opponent, though it is based on a single fixture.

With high confidence, the Poisson model projects a 2-1 Real Madrid win, with expected values of 2.78 home goals and 1 away goal. The most likely exact scorelines are 2-1, 2-0, and 3-1, each near 8.8%. About 3.8 total goals are expected, a 59.4% chance both teams score, and Real Madrid have a 54% probability of winning by two or more.

The data strongly favors Real Madrid: superior attack, best-in-league defence, and a home record that has held up over 20 matches. The main caveat is that this is the opening round, and Real Sociedad's attack ranked sixth, so they are capable of scoring. If Madrid do not convert their chances, the margin could be narrower than the model suggests.
