How we got this number

The league sets the starting point. Copa Sudamericana has produced over 2.5 goals in 40% of its matches, and that is where a team with no record of its own would sit.

Each side's own record. Boca Juniors have 7 in 22 this season (0 of 11 at home), Sao Paulo 9 in 22 (5 of 12 away). Those records are pulled toward the league rate with the weight of about 32 matches — enough that two or three unusual games cannot swing a rating — giving 30% and 41%.

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 36%.

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 28%, from expected goals of 1.19 for Boca Juniors and 0.65 for Sao Paulo. Folding in 30% of that view gives 34%.

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.
