He was forced from Milan because they couldn't afford his wages plus they got a nice amount selling him and T Silva. The only club who could afford his wages and wanted him (at that price) was PSG.
I don't think he's interested in PL either. He will probably stay another year at PSG or move to Italy. If he's moving to Italy and he takes a wage cut I can see Juve going for him. I don't see him going to Spain either (only option there would be Real Madrid). German league...hmm not sure.
Not sure about him staying another year at PSG though, he's way too good for that league and he knows it. He's probably capable of keeping his level for 3-4 more years as his play doesn't depend on speed so much as technique and strength.
We would have no troubles winning the league with him each year. CL however
Now you might not like him as a person but he's a top, top striker.
