I think people are a bit obsessed with him and Barcelona, just because he wants the Barca job doesn't mean he'll get it. I can't see him getting it anytime soon unless he's successful with us or his next club if he leaves.
He's in his mid fifties, been in management for 17-18 years and other than Valverde doesn't really seem to fit in with the age profile of recent Barca managers. He's a Barca legend yet has consistently been over looked for the job in favour of younger, less experienced managers even when he was assistant back in 2000. It would seem that Barca are more willing to take a go on a less experienced manager than someone who is becoming a bit of a journeyman manager. His style of play also doesn't fit in with Barca either.
