In a recent press conference new boss Gerardo Martino told that Barca will not be buying a defender during this transfer window. In fact he said that Barca doesn't need a centre-back, because they already have so many.
Well, let's take a look shall we:
Carles Puyol: a great player, yes. But there's no way to deny that he is getting older and that means that his speed is not the same, his stamina is not the same plus he's so prone to injuries that Barca really needs a solid back up for him.
Gerard Pique: not much to say about him. Has all the talent to be one of the very best defenders in the world and sometimes he is, but sometimes he seems so distracted while playing that I have several times wondered if he even realizes he's on the field. I don't mean to be harsh, I really love Pique, in fact he's one of my very favourite players, but it's just frustrating to watch that he doesn't always live up to his full potential.
