Matches with foul data
Feb 2025 – Sep 2026
On record
Penalties count converted spot-kicks only. There is no separate penalty-award record in the data, so a saved or missed penalty is not in that number and this is not an award rate. Fouls come from the match stats feed, which covers about four matches in five — the denominator is above.
