N'Koudou left Tottenham to join AS Monaco on loan until the end of the season.
N'Koudou, 23, had managed just three appearances for Spurs in all competitions this season, though two of those came in January. His excellent cross was met by Harry Winks to score a crucial winner against Fulham.
But Mauricio Pochettino has welcomed back Son Heung-min after the South Korean ace took part in the Asian Cup, and that has pushed N'Koudou further down the pecking order at Tottenham.
It saw Tottenham grant N'Koudou a loan exit and though there was talk of a move to Turkish side Besiktas, N'Koudou has teamed up with struggling Ligue 1 side Monaco in a bid to help them avoid relegation. Sissoko sent a Tweet to the winger.
Since joining Tottenham in the summer of 2016 from Olympique de Marseille for a fee of £9million (BBC Sport), N'Koudou has managed just 26 appearances for Spurs - scoring one goals and creating two assists.
N'Koudou could make his debut for Leonardo Jardim's side on Saturday evening, as they face Toulouse at home. Monaco will be desperate to win, having won just three league games all season.
