Napoli have agreed to pay Manchester United a £500,000 loan fee for Axel Tuanzebe following the end of his loan spell at Aston Villa.
Tuanzebe cut short his loan at Villa Park to join the Italian side until the end of the current campaign.
Napoli will pay a further £333,000 should they qualify for the Champions League plus an extra £165,000 if Tuanzebe hits a set amount of appearances.
Tuanzebe, 24, had joined Villa for a third loan spell at the start of the season but following just six appearances now looks to be out of favour following the arrival of new manager Steven Gerrard.
