According to a latest report on Get French Football News, Nkoudou is expected in London today to discuss personal terms and complete his medical examinations.
The 21-year-old is expected to sign a five-year contract, and then presumably the deal can be announced.
It was earlier reported Tottenham boss Mauricio Pochettino personally made a phone call to Nkoudou to assure him of his chances at White Hart Lane.
Michy Batshuayi, Steve Mandanda, Benjamin Mendy, and Nicolas N’Koulou have already departed from the Ligue 1 club this summer, and it appears another key player is on his way out.
Nkoudou had 10 goals and 5 assists to his name last season, after signing for Marseille in a €1.5m deal.
