Rennes chief Florian Maurice has reaffirmed plans to sell Eduardo Camavinga.
The 18 year-old midfielder is wanted by Manchester United and PSG as his contract runs down this season.
Maurice said: “I repeat, when a player arrives one year from the end of his contract, either he leaves or he extends.
"No concrete proposal is on the president's desk. We are still working to extend Eduardo, we still haven't made any progress at this level.
"There are three weeks left in the transfer window."
