Nice are on the trail of Boufal. They hope to get the player on a season long loan deal for the 2018-2019 campaign.
The attacking midfielder has no future at the Saints, given a falling out with manager Mark Hughes during the past season.
He only managed three goals in 50 Premier League appearances for the club, flattering to deceive in most games.
Marseille may also be interested, according to the Mirror. But it is Nice who have the most concrete interest.
