Nice president Jean-Pierre Rivere has revealed midfielder Jean Michael Seri has a €40m release clause in his contract and that the club will be powerless to stop him leaving should a bid of that size be submitted.
Seri has impressed this season, scoring six goals and adding a further nine assists with Nice enjoying a surprisingly good campaign. The club are set to finish third in Ligue 1 and qualify for the Champions League next season.
However, Rivere says he and the club will have to let the Ivory Coast international leave should a bid of €40m be submitted, with Premier League giants Arsenal and Spurs, as well as French rivals PSG reportedly interested in the 25-year-old.
He told RMC SPORT: "Seri has a €40m clause. At that price, he'll be free. Without it, we don't have the intention to sell him. Even if people don't take clauses seriously in France, they deserve some respect. If a club offers €40m for Seri tomorrow, he'll go."
Nice will hope to be active in the summer transfer window as they look to build on their impressive 2016-17 season, but Rivere could not state which players have been scouted or targeted.
When asked whether he could say which players would arrive in the summer, Rivere responded: "No. We worked a lot. There is a small difference in our progress, because today, there are players who want to come to us. Before, it was the belly dance and the Promenade des Anglais to attract them. Today, we have this small advantage. We have the players who are likely to.
"But if the players can agree, the clubs can tell you no. There is no certainty for now. We have files that are moving forward. But frankly, I can not give you any names. If Nice gives the name of a player, there are two-thirds or three-quarters of the French clubs who can buy it."
