Just a thought....but how about Pasquale Foggia ?
After what happened i don't think he'll get to play again for Cagliari and he'll get back to Lazio in January already.
Also, after his brilliant displays in the last 4 months i doubt Lazio can keep him, considering their salary-cap.
Foggia was sold to Lazio less than a year ago from Milan so i don't think Milan will pay a lot to get back the player they sold for peanuts in January.
Roma is out of the question so it leaves us and Inter (from the Italian teams)
I know we have a lot of midfielders and especially a lot MR's but with Camoranesi getting injured in every second match/training and since Sali and Marchionni don't offer much, Foggia may be the solution.
We'll get a very good player , who is only 24 and is becoming better with every next match and we might find the long-term solution for the right side of our midfield.
Of course, he should be ready to sit on the bench for a year or so because Camo is still better player than him. I'm not sure if he is ready for such sacrifice, though.
