I wouldn't stop at just Seba and Marchi...Bocchetti Balotelli and Motta should be there as well...something like:
Buffon (c)
Motta - Bocchetti - Chiellini - Zambrotta
Marchisio - De Rossi - Pirlo
Giovinco - Iaquinta - Balotelli
Yeah they should all be called up to the squad. Bocchetti is great. I dont know about all of them starting cuz the team chemistry would suffer alot and it is only a year leading up to the WC. It is hard ocnsidering they only meet a few times a year.
I think Canna will keep his place because he is captain but if he does not perform Santacroce and Bocchetti should be on the bench to replace him with Buffon taking the armband. Leggro and Gamberini should not be ahead of youngsters who are already as good or better than them.. they offer the squad no future. Lippi says the team needs continuity but how can the team have that in the end when the whole team is the same age pretty much and will all finish at the same time. There need to be youngsters behind the older players waiting to take their place.. not more old players.
With regards to motta starting. He is good but I think Santon is a better player and is more consistant ( Lippi probably does too seeing how he actually brought him to the tournament) I think Zambrotta and Grosso should be squad members but only play if they are in form. If not Santon/or Motta and Criscito can take their places respectively.
Balotelli, Giovinco and Rossi are the 3 best young attacking players Italy have and they will be the starter probably at the world cup in 2014 so it owuld make sense to at least have them as part of the team now... they are much better than Quag, Pepe and Camo at this point.
like the squad should be something like this:
-----------Buffon/ 2 other goalies who wont ever play-------------
Santon/Zambro--Canna/Santacroce---Chiellini/Bocchetti--Grosso/Criscito
Marchisio/Rino---Pirlo/D'Ago----De Rossi/Aqulilani
---------------Giovinco---------------------------------
Balotelli/Amauri/Iaquinta--------------Rossi/ Di Natale
That would be a very competitive team in every position forcing the starting 11 to up their game, would drop the avg age alot and would prepare the team for the future with young players coming to the fore as starters and squad players.
