I would go with:
Doni; Cicinho, Mexes, Juan, Tonetto; De Rossi, Aquilani; Giuly, Perrotta, Mancini; Totti
Cicinho doesn't need a rest as he barely featured in the first half of the season.
Giuly deserves a start, Taddei can start from the bench. I'm tempted to drop Mancini, but Vucinic is currently a bit of a supersub, so he can come on early in the second half. Amantino is in a slump.
