Is anybody spotting a theme?

Sheffield United - one sending off, one should have been sent off, one player in intensive care, one very dodgy penalty.

Sheffield Wednesday - one sending off, one should have been sent off, Kozluk lucky he didn't get his leg broke.

Chengdu Blades - two sent off, one should have been sent off, referee blowing for time early to avoid any more of their dirty challenges.

Dirty Leeds??? Dirty Sheffield more like.
