RMC report that Premier League side Watford have approached Nantes over the possible signing of 2001-born central defender Nathan Gassama.
The U19s player has for the moment seen Nantes refuse approaches from England, as discussions continue.
Watford want to integrate Gassama into the development programme, by loaning him to a partner club as the first step.
He still has another 2 years remaining on his youth contract. His little brother, Éden, has signed a contract with Guingamp recently.
