I'm not a Heskey fan at all, but I thought he did OK tonight. NRC I didn't think did very well. Yes, he has energy. Yes, he tried hard. But he lacked quality in every part of his game.
Getting behind the team is all well and good, but we should also be able to criticise players when we don't think they have performed well, otherwise there wouldn't be much point of this message board.
