Giovinco pulled up in training yesterday with a thigh injury and the Bianconeri confirmed today that the 22-year-old will be out of action for "25-30 days".

The former Italy under-21 international will miss the Serie A games against AC Milan, Chievo, Roma, Lazio and Livorno as well as the Coppa Italia tie against Napoli.

Giovinco joins Gianluigi Buffon, David Trezeguet, Vincenzo Iaquinta and Mauro Camoranesi in the treatment room, while Mohamed Sissoko is at the African Nations Cup and Martín Caceres is suspended for tomorrow's clash with AC Milan.

It is a big blow to coach Ciro Ferrara who is under pressure having won only twice in his past seven games.
