According to reports from Le Parisien, new Rennes president Nicolas Holveck would ask any potential suitor to pay in the region of €20 million (£18m) for M’Baye Niang.
Earlier this month, Daily Star claimed that Niang has been offered to clubs around Europe, with Premier League outfits Tottenham Hotspur and Brighton and Hove Albion also among the interested parties.
French publication L’Equipe claimed earlier this month that Spurs are showing keen interest in signing Niang in the summer transfer window.
Also, transfer expert Nico Schira has claimed this week that the 25-year-old is getting close to moving to French rival Marseille, with talks between the two clubs ongoing.
