If Napoli raised their bid and we can sell him for around 25M it would be a glorious chance.. He is not getting any better in Barca's system.. He proved mediocre in Dm position compared even to Song (for our style, i STRESS) and he proved reliable for some occassions in the CB positions, but with healthy Puyol a better choice even now that he is ageing..
This teams need to start learning WHEN to sell a player. We keep losing players for free when their value has touched bottom and its evident that they are below par, not going to rejuvenate anyhow.. See my comment on Cesc threat also regarding Villa..
The only problem is that Masch will not go to a team like Napoli, even with Rafa a a coach. He can play number Six for any top side in Europe besides barcelona..
