Serie A · Thursday, 29 October 2026 · 19:45. Our rating makes this 49% to go over 2.5 goals, so our lean is under. The Serie A average is 48%.
| Market | Yes | No | Our call |
|---|---|---|---|
| Over 2.5 goals | 49% | 51% | Under |
| Over 3.5 goals | 26% | 74% | no pick |
| Both teams to score | 52% | 48% | Yes |
The result model puts Fiorentina at 29%, the draw at 26% and Atalanta at 45%, from expected goals of 1.18 and 1.55.
The league sets the starting point. Serie A has produced over 2.5 goals in 48% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Fiorentina have 6 in 7 this season (3 of 4 at home), Atalanta 5 in 7 (2 of 3 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 56% and 53%.
Last season still counts, briefly. With 7 and 7 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 50% and 44%.
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 5 times in three years, producing over 2.5 goals in 40%. 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 47%.
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 52%, from expected goals of 1.18 for Fiorentina and 1.55 for Atalanta. Folding in 30% of that view gives 48%.
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 49%.
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.
