Flamengo v Santos — prediction, stats and goal analysis

Serie A · Sunday, 5 April 2026. Final score 3–1 (half-time 0–0). Rebuilt from the season as it stood that morning, our rating would have been 52% for over 2.5 goals. This match is older than our frozen ratings ledger, which keeps 30 days, so that figure is a reconstruction from pre-match data rather than a number we published at the time — a distinction worth making, because only the frozen ones prove what we actually said beforehand.

The result model puts Flamengo at 76%, the draw at 16% and Santos at 8%, from expected goals of 2.35 and 0.59.

How we got this number

The league sets the starting point. Serie A has produced over 2.5 goals in 46% of its matches, and that is where a team with no record of its own would sit.

Each side's own record. Flamengo have 5 in 8 this season (1 of 3 at home), Santos 5 in 9 (3 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 50% and 49%.

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 49% and 48%.

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 48%.

Head to head. These sides have met 4 times in three years, producing over 2.5 goals in 75%. 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 50%.

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 56%, from expected goals of 2.35 for Flamengo and 0.59 for Santos. Folding in 30% of that view gives 52%.

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.
