Rennes attacker Ismaila Sarr wants to join Watford.

L'Equipe says Sarr has told his Senegal teammates that he wants to move to Vicarage Road and that Watford are optimistic of completing a deal, with talks over a potential deal continuing.

Rennes president Olivier Letang said: "With Ismaila there was a kind of gentleman's agreement, but it is necessary that conditions are met.

"As of today, they are not."

Sarr scored a total of 12 goals in all competitions for Rennes last season, helping them to a 10th-place finish in Ligue 1.
