Crystal Palace are increasingly confident of signing Lens midfielder Cheick Doucoure from RC Lens in an £18million deal.
A Palace delegation was in France on Tuesday evening discussing further add-ons that would push the price towards £22m plus a sell-on clause.
The 22-year-old has been Palace's number one target this summer.
The Mali international is expected to sign a five-year deal with Patrick Viera's side after impressing the Palace manager with his displays for Lens last season as they finished seventh in Ligue 1 in their second season back in the top flight of French football.
