Gibson's not amazing but he's good for a squad player, I kept him and he chips in with around 5 goals a season when he does play which isn't often. Developed right, Petrucci becomes really good and Macheda's PA changes from game to game I think so whilst he is ocassionaly really god, he can often be quite poor. I usually sell him and welbeck and raise about 15-20 million between them.
