Any formation is fine by me provided we have the right players and coach to play it. Every big team plays differently, inter, barca, arsenal, united, chelsea....all differ...but they have the players to pull off whatever their coach is trying to dish out.
The 4-4-2 interests me as i think it will bring some stability back to the team, we looked poor structurally all season. cassani, criscito, bonucci, vargas and a few other important signings and we may be back in business.
