Amiens are holding fast to their price for Serhou Guirassy.
The 24 year-old striker was a revelation for Amiens this season and attracted enquiries from England.
Rennes have offered €15m for Guirassy, however Amiens are refusing to budge on their €20m assessment.
Brighton, West Ham and Arsenal have all expressed interest in the striker this past Ligue 1 season.
Amiens were willing to sell Guirassy for the right price in January and the club instructed intermediary Mark McKay to sound out interest from England in the striker for the next two transfer windows.
