Here, we take a look (via WhoScored stats) at the 2020/21 Championship's disciplinary figures including fouls, bookings, red cards, and examine where Luton Town rank among every other second-tier side in the 'dirtiest' teams league table.
We've awarded half a point for a foul, one point for a yellow, three for two yellows followed by a red, and five for a straight red. The teams are ranked from dirtiest to cleanest and we've also included each team's most ill-disciplined player for good measure:
