Sissoko and Marchisio would be perfect for the 4 2 3 1, the latter could link up well with the attackers. His short range and long range passes are getting better, he's turning out to be our midfield engine. And that pass to Trezeguet against Bayern, just splendid.
I'm just very happy we have a player like him. He's truly fulfilling his potential. Truly a force to be reckon with.
