I think it's abit of reverse psychology from Gus, he's trying anything ATM to get something out of the players. I commend him for that.
Poyet said he rather play 4 at the back but because the players like playing 5 at the back then his going to keep on playing 5 at the back. he is a weak manager sorry.
Managers say a lot of things, 4 at the back, 3 at the back etc doesn't mean it's going to happen. Gus is all we've got! I cherish that!
