Right, I get your point now, but disagree that it's because of fear. I really think he wants to see two successful formations for this team, and chance creation in some of the 3-5-2 matches (Roma Coppa, Milan Coppa, Parma) haven't been lacking. Another successful coach has been trying to use a second system lately as well.
Guardiola has been succeeding with his 3-4-3, if this is what you were implying. And again, Guardiola have a totally different squad than Conte, a squad of players much more capable of giving and adapting.
Maybe Padoin should be used as rwb if aren't willing to risk Licht.
Edit: As I posted this the official lineup were released: Buffon; Barzagli, Bonucci, Chiellini; Giaccherini, Marchisio, Pirlo, Padoin, De Ceglie; Borriello, Quagliarella.
Can't see us getting a penalty, anyway. The backlash would be incredible. Accusations of "bowing down" to Juventus and all that. FIGC won't stand for it.
it almost seems like Conte is pulling a Ferrara here... ditching a formation that has worked for us all season for one which has provided only bare minimums...
