Oh I don't miss the douchebag/diva thing being away from Barca at all.
However AG is a brilliant and technical footballer. Control, touch, pace, sharer of the ball, great at anticipating movement, good work rate off the ball, good shot. Great player and I think would work tremendously with Messi personally. I also think he is far better for team chemistry than say Hazard. AG has the douchey stuff off the pitch and after he scores, but can't complain about how he plays with a live ball. Rather have that than a nondouchey off the pitch player who is a little selfish or just doesn't read where his teammates are going very well or sulks when things are not going to his individual liking.
Rabiot was only if interest because he is a talent on a free and if we sold some of our midfield size (Rakitic/Busi).
