New Siena signing Emanuele Calaio admits he left Napoli because of a row with coach Edy Reja.

The experienced forward said: "I'm not sure if I will wear the Azzurri jersey again. One thing is certain; I'll come back only if there is another coach and if Reja leaves.

"However, this isn't going to happen at Napoli, who are happy with their coach.''
