The result model puts Bayern München at 49%, the draw at 27% and Arsenal at 24%, from expected goals of 2.37 and 1.11.
The league sets the starting point. Champions League has produced over 2.5 goals in 60% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Bayern München have 5 in 6 this season (3 of 3 at home), Arsenal 4 in 7 (1 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 65% and 60%.
Last season still counts, briefly. With 6 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 75% and 57%.
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 65%.
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 67%, from expected goals of 2.37 for Bayern München and 1.11 for Arsenal. Folding in 30% of that view gives 66%.
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.
