Honestly though, although I love Pato and I think he will be one of the best players if not the bes in a few years, I think 55 million + Benzema is an amazing deal. It would probably have a Zidane to Real or Ibrahimovic to Barcelona type of effect on their team. 120 million(For Pato and Kaka last year) in a year + Benzema is a crazy good deal for Milan. Now they could easily rebuild their team and sign a bunch of top class players for their team. After all, for their 4-3-3, they are really in need of a goalkeeper, two fullbacks, at least one new central midfielder, and a right winger.
Just for fun:
Lloris
Zambrotta - Nesta - Thiago Silva - Tremoulinas
Yaya Toure - Pirlo
Gourcuff
Krasic - Benzema - Ronaldinho
My god, that team is intimidating.
But then again, this is still Milan we're talking about and they would probably sell him, keep the money, sign a few oldies and scream that they don't have any money at all.
