Simone Zaza has described Napoli as a 'great team' but insists he would be a 'failure' if he were to leave West Ham after just a few months in the Premier League.
The Italy striker has yet to score in nine appearances for the Hammers during his loan spell from Juventus and has been strongly linked with a return to Italy in January.
Napoli would be one of the frontrunners to sign the 25-year-old should his time at West Ham be brought to an end.
The terms of his deal state that West Ham must sign Zaza for £20million if he accumulates 14 appearances for the club.
