Napoli have Ezequiel Lavezzi back on the bench, but stick with Goran Pandev for their tricky trip to Siena.
The Partenopei have effectively a full squad to choose from, as Lavezzi has recovered from a month out with a thigh strain.
He is not yet fit to start, though, so Pandev maintains his spot with Edinson Cavani and Marek Hamsik.
Siena beat Lazio 4-0 here in their last home outing, so confidence is high, although Luca Rossettini and Alessandro Gazzi sit out bans.
Goalkeeper Zeljko Brkic is injured, so Gianluca Pegolo takes the gloves, while Franco Brienza and Emanuele Calaio are chosen in attack.
Siena: Pegolo; Pesolo, Terzi, Contini; Vitiello, Bolzoni, D'Agostino, Vergassola, Del Grosso; Brienza, Calaiò
Siena bench: Farelli, Belmonte, Parravicini, Angelo, Reginaldo, Gonzalez, Destro
Napoli: De Sanctis; Campagnaro, Cannavaro, Aronica; Maggio, Inler, Gargano, Dossena; Hamsik, Pandev; Cavani
Napoli bench: Rosati, Fernandez, Britos, Dzemaili, Zuniga, Vargas, Lavezzi
