I don't disagree, but, like I mentioned earlier, we have Nedved, Camo, DP and Trez and as long as we have these guys we will always fit perfectly with 442. I am not against the 433, but the formation doesn't dictate the play style. 442 can be a creative formation too. It depends on he philosophy of the team.
Regardless, we will never be able to play "free" flowing football unless we can defend and win balls. Nocerino is our best hope. The guy is a beast and is the ultimate destroyer. He is young and needs to tone it down a bit, but sometime when you tell players like him to do that, it takes them away from what they are good at. Gattuso makes a lot of silly penalties, but you have to weigh his good vs. his bad. I don't want to compare Nocerino to Gattuso, but they are similar, just on different levels right now. Zanetti would work for now as well, but he isn't as physically gifted or as influencial. Almiron needs to be able to move up with out having to worry about creating a huge gap. If Nocerino is in, he can focus more on attack.
We definately need a LB and shift Chiellini to CB. Or we need a CB and keep Chiellini outside. No doubt about it.
Anyways, I don't think that the formation leads to free play, but philosophy does. I am a fan of defensive football. But that doesn't mean teams like Milan aren't defensive. They play very defensive, but hold posession when they win the ball back. We could be like that with our players, but somewhere in between where we used to be with Capello and where Milan is with Anceloti.
