He is going to Man city anyway...
Our best chance of signing Rossi would have been, give them Poulsen (10mil) they really want him!
Sell Treze 10-15mil and sacrifice our depth in the midfield and needs in the defense to get Rossi. That move would totally cancel Giovinco, as he would never find a place with both Diego and Rossi in the team (not to mention DP)
And early retire DP...
