Not at all, but only IF he played for the team, not himself, IF he gave the manager 100% respect, IF he did the same with the fans, IF he kept his gob shut when dealing with the press, IF he acted less like a prick off the pitch in general and IF he wanted to play in "that shoebox" again.
I think there might be a few too many IF's there to make the decision viable. Leon, you were a legend until you pressed self destruct. Everyone can change, but you'd have to change your entire personality to be welcome here. I'm sorry, but I can only think bringing you back would be a recipie for disaster for the dressing room, the manager and what he is trying to do. It's a total non starter.
This. Obviously. Disagree with this and frankly you know nothing about management of any kind.
