Cruz for Ibrahimovic?? You can't be serious. I don't care how much people on this forum hate him, Ibra is worth FAR, FAR more than a 32 year old Julio Cruz.
Sell Ibr off to the highest bidder, and use some of that money on Lucarelli, although I'm not a huge fan of his, if Juve is going to play a 4-3-3 formation, (Let's face it, they'll have to if the penalty stands, on order to get as many goals as possible), then you'll need three proven goal scorers up front.
Lucarelli, Del Piero, and Bojinov in Serie B would do just that.
