It's more proof he will never change. Barca would be stupid to buy him but Barca have never shown an awful lot of integrity or sense... just look at the Neymar deal that will potentially cost the club 150mil after being fined for evading the tax on the deal.
Which is entirely my point.
That if Barca want him, they will go for him regardless of what issues he has. This ban only becomes relevant if its a HUGELY lengthy ban.
