Juventus boss Antonio Conte will field a 3-5-2 against FC Copenhagen on Wednesday, but he does have a few doubts about his starting XI.
Having used a 4-3-3 against Real Madrid in their last two European Cup games, the tactician will revert to the system the Old Lady presently use in Serie A.
Conte, though, will be without Andrea Barzagli and so will have to choose between Martin Caceres and Angelo Ogbonna.
If the Uruguayan is fielded in the back-three then Simone Padoin will be used on the right of the midfield five.
If Ogbonna gets the shirt, then Caceres may be asked to play on the right-wing instead.
There is also the possibility that Arturo Vidal may be rested given that he is one booking away from a suspension and Juve will need a result at Galatasaray in their last group game.
Juventus probable: Buffon; Bonucci, Ogbonna, Chiellini; Caceres, Vidal, Pirlo, Pogba, Asamoah; Tevez, Llorente.
