Club over country for me.
And Andy, Rossi will be a megastar. The sooner you deal with it, the better it will be for your sanity. Otherwise you are going to spend your next 50 years in frustration, or at least 15 or so years until he retires
Oh, and btw, I am not a fanboy. I just think Rossi is a fantastic player (who still needs to improve, and has the potetnital to be one of the best), but I won't lose sleep over us not signing him, retaining Trezeguet instead of acquiring him, or buying another forward/striker altogether
