I think LFC have had far more erratic players that Suarez playing for them. As far as I can see, he's done nothing wrong yet!
Hasn't cleaned anyone up badly, hit anyone, spat on anyone, touched a ref, only an accusation by 1 player that abused him.
He's performed consistently as a gun player and that's all LFC ask of him. Yellow and red cards are part and parcel of the game, ask Rooney and Scholes about that.
