Tanguy Ndombele is reportedly set to leave Tottenham Hotspur on a permanent deal next year.
The Frenchman's £200,000-a-week contract expires in 2025, however he is not part of Antonio Conte's long-term plans.
Football Insider reports that his loan deal with Napoli contains a £30m option to buy, triggered if the Italians secure qualification for the Champions League.
Luciano Spalletti's side are well placed to do so, considering they sit top of Serie A, eight points ahead of last season's winners AC Milan, and topped their Champions League group, ahead of Liverpool, last season's runners-up.
The former Lyon midfielder has made 18 appearances in all competitions so far, including six starts in the league and two in Europe.
Tottenham are reported to be increasingly confident that the permanent transfer of Ndombele will be completed, however a January transfer is seen as unlikely.
