Napoli have snapped up released Fiorentina midfielder Mario Alberto Santana.

Santana was a free agent after his contract with the Viola expired over the summer and had a deal with Napoli some time ago, but it was only made official this evening.

The Argentine is 29 years old and has been in Italy since January 2002, playing for Venezia, Palermo, Chievo and Fiorentina.

Santana joins another former Fiorentina player who was a free agent, Marco Donadel, at the Stadio San Paolo.

Napoli also confirmed the arrival of goalkeeper Roberto Colombo from Triestina.
