It seems that you forgot what Cambiasso does when he plays box-to-box. Where is he playing now? With Samuel and Chivu Cambiasso will lift the team forward more than you can imagine and still cover defensively. Players like Figo will not start.
You're right about Cambiasso's influence.
But the system won't change, Jack. Cambiasso will replace Stankovic in this line up, not Figo.
Mourinho will keep playing 4-3-2-1, with Zanetti-Cambiasso-Muntari in midfield, Figo/Ballotelli (maybe Quaresma) - Mancini on the wings and one striker.
As you can see, it's a hard working midfield. Unbreakable midfield. The only way to beat this is to play on the wings but Maicon and Maxwell do a good job there.
This is your typical serie A winning team. Team that plays without the so highly rated creative midfielder but relies on strong defense all over the pitch and very strong attack.
We have the same hard working midfield and we have the strong attack. With Chiellini and Buffon we can allow an average Cb partner for Chiellini. But we can't allow the defensive mistakes our full backs make.
Trust me, if we had Maicon and Maxwell and if Inter have Grygera and Molinaro, we'll be the better team.
