The Championship's dirtiest teams - where Sheffield Wednesday, Hull City, Leeds United, Middlesbrough, Huddersfield Town and Rotherham United rank

The second tier of English football is a fiercely competitive division.

Stakes are incredibly high, with the Premier League and all the riches it comes with a possibility with promotion.

However, relegation to League One is also a possibility and can set clubs back years when it comes to growth.

These factors help create an intensely physical and closely fought league, and mean tensions can sometimes boil over.

Using data sourced by Transfermarkt, here is a ranking of the Championship’s ‘dirtiest’ teams.

The table has been compiled using a points system – a yellow card counts as one point, a sending off because of two yellow cards counts as three and a straight red counts as five.
