Does Pep want him though?
From a team perspective, Xavi is now over 30 and needs a replacement. Fabregas is almost tailor made for it. So I don't think you'd hear any Barca manager complaining about having Fabregas bought for them.
Mind you, there'll be all kinds of silly stories coming from Barca until the elections are held in June and you'll see half the top players in the world promised on a wink and a nudge if you listen to all the presidential candidates.
