The Gabon international has been in great form at Lorient.
They report that Southampton have been watching the player and are impressed by what they have seen. Both Southampton and Stoke are therefore expected to make a move for the player.
However the report claims that he will not be sold until the summer and if he does go it will not be for less than €10 million (£7.75 million).
Ndong is a Gabonese international who only joined his current club in 2015 after four years playing for CS Sfaxien in the Tunisian top flight.
He impressed in North Africa and has been at Lorient for a year now and has earned big plaudits for his performances in French football.
Ndong has played 21 times this season and scored two goals for the club as he continues to catch the eye with his all action midfield displays in Brittany.
