It does make you wonder sometimes. The 'top 6' (or top 4) have so much more money flowing in due to European competitions, and hence so much more money at stake, that it does make you wonder if refs are 'more concerned' about the top 4/6 clubs winning at times.

I wouldn't usually think of conspiracy theories and all, but when you look into the murky world of agents and how dodgy some deals are when there's big money at stake, why can't refs be 'slightly' corrupt..?
