I think that he would be fine staying but with a release clause so low he will have very good offers.Better deal would be keeping Hernandez and having him push Filipe Luis for the position. Unless he wants to leave Atletico so badly? I'd rather play Filipe and get somebody else useful from Barca or more money. Maybe I am biased because Alba is one player I just can't stand.
Some weeks ago they wrote as well about Madrid.
Although I like him I guess that Barsa would be a good option.
In Madrid he would have to compete against Marcelo.
