Pires won't be expensive. The fact that he is being linked to Galataseray proves that.
I have no problem getting a 32 year old if he can last a couple of seasons, is world class and we can get him cheap.
That is Pires for you. Therefore, if we decide to loan out Olivera and given that Kapo` is already loaned out, Pires is a great alternative because he can play on both flanks. That way, we only need 7 midfielders this season:
Camoranesi, Emerson, Vieira, Nedved, Pires, Giannicheda and Blasi.
Worst case scenario is if Neddy and Camo both get injured....then we still have Zambo and Chiellini who can play as wingers too. therefore, I think Juve would have plenty of depth on the flanks if Pires arrived.
