Unfortunately for Arsenal, Manufactured City and Chelsea will forever be in your way to the title, even if United slip up (which I doubt they will). Fab knows that better than anyone. All joking aside, you must now face up to the fact that Fab will leave. Let him go with dignity.
I think we all know that one day he'll go back to Barca. But the last thing he said was that he was happy at Arsenal and looking forward to winning trophies with us. He has also said that he's not going to push for a move to Barca, they cannot afford him and Wenger will not sell to them. So best thing for all parties is to drop it really. But of course it's silly season and the papers and wums need material to feed on.
