Unfortunately, it's a game where even fantastic players like Trent, Virg' and Allison are still capable of making simple and obvious mistakes. And when they do, very few of us think, "OK I'll let him off that one because of all the good things he's done in the past". The natural and immediate reaction is to react.
It's mostly just short-term, knee-jerk stuff anyway. I don't take it too seriously when I read it.
You'd honestly have to be mad to believe that such and such a player is actually sh*te, lazy, or just plain gash. They're professional footballers playing for the best team in the land.
