Napoli have signed Argentinian winger Mario Alberto Santana.

Santana has joined the Naples outfit as a free agent after leaving Fiorentina last month.

The 29-year-old has penned a three-year contract with Walter Mazzarri's side.

Santana becomes Napoli's third signing in a week following the arrival of Swiss midfielder Gokhan Inler from Udinese and Uruguay centre-back Miguel Angel Britos from Bologna.
