Think it is a psychological issue tbh, when you have every other fan in the league desperate for you to fail (for what reasons I still don't understand) it is almost inevitable that you will, I think this is something which has existed for a while but Fergie was always shielded us from it, by having the media in his back pocket etc.. However now that this is getting through to the players, it is easy to identify that there is something wrong with the players psychology and confidence on the pitch... Call in the sports psychologists I say.
