As expected, Napoli have officially signed Emanuele Calaiò, while Siena loaned Matias Martinez to Argentinos Juniors and Cagliari released Rui Sampaio.
Siena had already confirmed the deal was done for Calaiò to the San Paolo, but it was formalised this afternoon when he put pen to paper on a contract.
The striker, who turned 31 earlier this week, has arrived on loan with an option to buy at the end of the season.
It is a return to Naples for Calaiò, who played for the club from January 2005 to June 2008 with 44 goals in 128 games in all competition.
In other transfer news, Matias Martinez has left Siena to go on loan to Argentinos Juniors.
The 24-year-old centre-back is still owned by Racing Club and interrupted his loan spell in Italy after just six months.
Cagliari-owned midfielder Rui Sampaio had been on loan at Olhanese, but has instead been sent to Beira Mar, one of his former clubs.
