Yet somehow I don't remember you coming in here saying he should fuck off when he is banging in the goals. You certainly weren't here when he hattricked West Ham. When things go south, everyone rushes in to express their views that they held in the closet for so long. Sanchez has contributed at least one goal or assist for this team in the EPL this season alone 15 out of 24 times (63%).
No, Wenger wants that. Sanchez and Ozil have a Wenger free pass to do what they want on the pitch. Do you really believe that someone who doesn't follow tactical instructions and interferes with the style of play would be on the team sheet? And you are right, Ramsey, Xhaka, El-Neny and Coquelin speed up the pace of our game tremendously, while Sanchez cocks things up.
Actually Barca let him go because they wanted Suarez whom I am only guessing they considered the better player (hardly arguable) and they needed to open up funds as well as first team space for him.
Also I have to disagree about the selfish part on behalf of Sanchez. I agree he holds on to the ball for far too long at times but the motivation is different from being selfish. He actually always releases the ball to Ozil when he is near. He just doesn't trust the others to create. And it is understandable, when you are surrounded by the likes of Ramseys, Chamberlains, Walcotts, Coquelins and you are the best player in the team, no wonder you will think you will do a better job with the ball than they will.
