Since this game is played already after such a short period and we have tricky away trip at Munich next week, we surely should think about some rotation here.
Not knowing the state of DP nor Diego, i would play Iaquinta and Trezeguet from the start. And rotate between Camo and Gio. If either of DP or Diego is back then its a good bonus, give them 45 minutes or bit less. Since this is just Bologna. We need to be ready for Munich. Its quite important to get something from the next CL game, since Bordeaux play the group outsiders.
