He wont fill that gap, he will be out of position and struggling to get back into it.
No he won't. You are forgetting this is Barcelona, not Arsenal. At Arsenal, he was one of the best players. He had to do a lot work because players around him were either adapting, not good enough or young.
At Barca we have players who don't need help with the attacking side of things so he doesn't need to be busting a gut to help them out and when they lose it, running his arse off back to help the defence, like he did at Arsenal. If he does come, he will be instructed to hold his position, not what Wenger was telling him to do.
Having said that, I still don't think we need him.
