How the numbers are calculated
Cards = yellow and red cards shown to players during 90 minutes (a second yellow counts as a yellow plus a red, as most bookmakers settle). Cards for coaches and substitutes on the bench and cards in extra time are excluded. Penalties = penalties awarded during the match (shoot-outs excluded). โvs leagueโ compares the referee with the average of the exact league seasons this referee worked, so a referee from a card-heavy league is not called strict just because of the league.
