I am not sure changing a manager will help. Somehow, the players just do not have a mean streak in them. It is in the collective psyche of the players. A team who comes back often from a goal down will believe it can be done. One who does not, start to doubt themselves when they go behind. It is a vicious cycle. The longer it goes on, the greater the doubt. How many times did we come from behind to win a game? Maybe once this year, against WHU.
