Lille will listen to offers for Arsenal target Eden Hazard, but will only consider those upwards of £43million.
Arsene Wenger has been tracking the Belgian playmaker for some time, even having an approach turned down in the summer.
The latest comments out of the French club will dismay Wenger, as Arsenal may have been priced out of any attempt to bring Hazard to Emirates Stadium.
The Gunners know they have been competing with the likes of Real Madrid, Paris St Germain and Manchester United, but were thought to be confident they could seal a deal.
Lille chairman Michel Seydoux accepts Hazard will leave eventually, but only for the right money: "The price is €50m and this is clear in advance.
"We are at a time when the club is having a real discussion about what to do but it will depend on many factors," he said.
"First, our economic potential and then it depends on the proposals we receive.
"Nobody is unsellable and you would be able to look for solutions in the market with the money we'd receive."
The Belgium international has been courted by Europe's elite for some time now, and has admitted he is ready to take the next step in his career.
Lille's stance comes in light of the fact they are considering making the loan transfer of Liverpool playmaker Joe Cole permanent.
Were he to join Arsenal, Hazard would line up with compatriot Thomas Vermaelen and former team-mate Gervinho.
