Some would say when you're a good player there's no need to be snide, but we've seen plenty of excellent players who have been complete c*nts into the bargain, and I know we've often felt a twinge of envy. Think Costa was a bit like that.
There's no need for it every game imo but it's good to have players who can be like that and turn it on when playing the shithouse teams who want to kick or shirt pull you out of the game. Nobody wins the league these days by playing nice.
