We've taken a look at the number of yellow and red cards Championship sides have had this season, as well as the total number of fouls (via WhoScored data), and awarded half a point for a foul, one for a yellow, three for a yellow/red and five for a straight red to calculate the 'dirty' rating. Here's a look at how Barnsley and their divisional rivals rank in the table.
