Bologna’s yellow cards in the Champions League and in the league

, ,

Against what the season’s ratings expected, Bologna was 2.5 yellow cards over in the Champions League and 0.1 yellow cards under in the league over its last 75 games, 3 games against 72. The plain averages are 4.7 and 1.7, a difference of 2.9.

3 games in the Champions League is still too small a sample for the statistics to say much, but maybe you can find something if you squint.

Method

Read against .

  • Expected is an offense and a defense a team, fit over every game of its season between two teams in the table with the game being read left out, minus 0.1 in 2024-25, minus 0.1 in 2025-26, minus 0.1 in 2026-27 for the home team (the edge the fit finds once strength is in), nothing at a neutral site.
  • Each expected number is then fit to the season’s games: a game bears out about 63% in 2024-25, 56% in 2025-26, 25% in 2026-27 of the difference the model predicts.
  • The shuffle keeps the season’s shape: the games are cut into stretches, one a 10 games, where the dates leave the least variance, each game is read against its stretch, and the sides are shuffled only inside each stretch.
