Simon is a subject of interest from OGC Nice, Leeds United, and Brighton & Hove Albion.
There were reports that OGC Nice had agreed personal terms with the former Nantes player.
Nice are also willing to pay €10m for Simon.
According to L’Equipe, Nantes, however, valued Simon at €15m.
The pacy winger played a key role in the Canaries Coupe de France win last season.
He scored six goals and recorded eight assists in 30 league appearances for Nantes.
