I would pick this:
Buffon
Licht-Barza-Bonucci-Chiellini*
Pirlo Vidal
Krasic Del Piero Pepe
Vucinic
*(Since DC isn't playing)
Pirlo should sit back and dictate play while being protected by Vidal. Vucinic & DP can use their dribbling to work some magic in and close to the box while Krasic and Pepe stretch Milan's defense. I think it would create a lot of space for DP and Vucinic because their defensive midfielders would try to shut out Pirlo while the wingbacks would have to deal with Krasic and Pepe.
