Adriano and Alba are both very good, but both aren't solid defensively...
I'm with the idea of buying a full back who's solid defensively!
Most Barca fans are talking about buying 2 Center backs, IMO we need 1 CB and a defensive minded FB.
I mentioned Filipe as an example, but I don't think he'll cost too much. We can swap Adriano+cash for him... Atleti seems to have a good relationship with Barcelona (Villa's deal). Anyway, I'm surprised that he's never been linked with Barcelona recently! We should have bought him instead of Alba!
