Lens are refusing to budge on their price for midfielder Cheick Doucoure.

Doucoure is a priority target for Crystal Palace boss Patrick Vieira - though Lens' asking price is proving a problem.

Lens are insisting Doucoure won't leave for less than €25m, which is far too steep for the Eagles.

Palace have already offered €17m for the 22 year-old, but the proposal was immediately rejected.

Doucoure scored one goal and made four assists in 37 matches for Lens last season.
