I don't know when will his contract expire. If it's summer 2012 then canceling his contract in January will cost us around 6-6.5m eur, I think. Needless thing to do.
Then again, if he does a Tiago and decides to just sit in Turin and get his money, then we will have to pay around 12m eur (including taxes) until his contract expires.
The smartest thing to do is to wait till the summer and see if we can sell him. If not, then cancel his contract and save some 4m eur that we were gonna pay for the taxes.
Or maybe he'll get back to the 2008 form and we might let him play the last season of his contract (sorry Hustini
)
