Napoli have signed Argentinian midfielder Jose Sosa from Bayern Munich for an undisclosed fee.

Sosa has struggled to hold down a first-team place at the Allianz Arena following his move from Estudiantes in 2007, making just 35 Bundesliga appearances for the Bavarian giants.

The 25-year-old has recently been on loan at Estudiantes but will now return to Europe to link up with Napoli.
