Edinson Cavani's house was burgled while the striker was away on international duty with Uruguay, the police in Naples said on Sunday.
Thieves made off with some gold necklaces and clothing, including a pair of the Napoli star's football jerseys.
The burglary took place in the early hours of Sunday morning during which time there was noone in the house, which lies between Bacoli and Pozzuoli outside Naples.
The burglary was discovered by some neighbours, who called in federal carabinieri police, on Sunday morning.
Cavani is away on international duty in Uruguay and scored in Friday's 4-2 victory against Bolivia in a 2014 World Cup qualifier.
