They tend to do it as soon as they think they can't cut it before anyone else realises so they get a few bob.
EDIT: Barca do not sell good players unless they have no choice.
Quaresma?
He was terrible at Barcelona.
Indeed he was, just like Simao. But apparently Quaresma never settled, to much to young and all that. Ive seen Chelski have been linked with him today actually.
Quaresma is fucking class bad he was awfull during his Barca days.
