The result model puts Barcelona at 83%, the draw at 12% and Alaves at 6%, from expected goals of 2.94 and 0.67.
The league sets the starting point. La Liga has produced over 2.5 goals in 51% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Barcelona have 8 in 9 this season (3 of 4 at home), Alaves 5 in 10 (2 of 4 away). Those records are pulled toward the league rate with the weight of about 24 matches — enough that two or three unusual games cannot swing a rating — giving 61% and 51%.
Last season still counts, briefly. With 9 and 10 games played this season, last season's rates are still blended in and fade out entirely by game 40 — the point at which our testing showed they stop adding accuracy. A single season is part luck, so each club's record is first pulled toward the league average by 34 games' weight. That moves the two figures to 63% and 51%.
The mix. Weighted 40% home side, 40% away side and 20% league — the split that beat every alternative across 30,582 matches of testing — that gives 55%.
Head to head. These sides have met 6 times in three years, producing over 2.5 goals in 67%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 56%.
Goal expectation. Separately a Poisson model built from attack and defence strength — using real expected-goals data where the league has it — puts this match at 70%, from expected goals of 2.94 for Barcelona and 0.67 for Alaves. Folding in 30% of that view gives 60%.
This breakdown is generated from the same inputs the rating uses, so it cannot describe a calculation we did not perform. The full model is set out in the methodology.
Our numbers give this match a 70% chance of at least one goal before half-time and 36% of two or more. The La Liga rates, last season and this season combined, are 69% and 34% (this season so far: 67% with a first-half goal, from 90 games). After the break: 84% for a goal and 55% for two or more (league 82% and 45%). Barcelona's last 50 games had a first-half goal 80% of the time and a second-half goal 88%; Alaves's last 50, 60% and 84%. A goal in both halves: 57% (league 57%). Highest-scoring half: second 47%, first 30%, level 23% — close to the league's usual split, because team form says little about which half is busier. Team form says less about a single half than about a full match, so these numbers stay close to the league's.
Every match ranked the same way: first half goals today · second half goals today · goal in both halves today · tomorrow.
