Watford centre-back Younes Kaboul is being linked with a move to France.
Kaboul, a veteran defender who is not in the first team picture at the club, is being linked with Nantes.
And Watford manager Javi Gracia cast doubt on his future when he said the player was fit but not training with the first team.
Kaboul signed for Watford in 2016, but has only made 26 appearances in the subsequent two years.
The 32-year-old is seen as surplus to requirements.
