La Liga · Saturday, 31 October 2026 · 15:15. Our rating makes this 43% to go over 2.5 goals, so our lean is under. The La Liga average is 51%.
| Market | Yes | No | Our call |
|---|---|---|---|
| Over 2.5 goals | 43% | 57% | Under |
| Over 3.5 goals | 21% | 79% | no pick |
| Both teams to score | 52% | 48% | Yes |
The result model puts Rayo Vallecano at 35%, the draw at 34% and Celta Vigo at 32%, from expected goals of 0.92 and 0.87.
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. Rayo Vallecano have 5 in 8 this season (2 of 3 at home), Celta Vigo 3 in 9 (0 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 54% and 46%.
Last season still counts, briefly. With 8 and 9 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 46% and 47%.
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 47%.
Head to head. These sides have met 6 times in three years, producing over 2.5 goals in 50%. 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 48%.
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 27%, from expected goals of 0.92 for Rayo Vallecano and 0.87 for Celta Vigo. Folding in 30% of that view gives 41%.
Calibration. Tested against 97,729 past matches, our ratings below 55% have run consistently too pessimistic — a figure in the high 30s, for instance, has come in about four points higher. So ratings in that range are lifted part-way back, giving 43%.
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.
| Team | Games | O2.5 | O3.5 | BTTS |
|---|---|---|---|---|
| Rayo Vallecano | 8 | 63% | 38% | 100% |
| Celta Vigo | 9 | 33% | 11% | 44% |
Our numbers give this match a 69% chance of at least one goal before half-time and 30% of two or more. The La Liga rates, last season and this season combined, are 69% and 34% (this season so far: 66% with a first-half goal, from 89 games). After the break: 83% for a goal and 45% for two or more (league 82% and 45%). Rayo Vallecano's last 50 games had a first-half goal 76% of the time and a second-half goal 82%; Celta Vigo's last 50, 60% and 84%. A goal in both halves: 59% (league 56%). Highest-scoring half: second 47%, first 29%, level 24% — 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.
