Rennes coach Julien Stephan concedes Desire Doue is likely to leave this summer.
The midfielder is a target for Manchester United, Arsenal and Tottenham, says the Daily Mail.
Rennes want 35m to sell Doue over the close-season.
Stephan said: "We know today's market, notably for the very young players.
"He will decide through his personal ambition. I'm not naive.
"We're glad to have developed him during the second part of the season. He's at risk of leaving without a single full season here, that's a shame. I would have liked that; that would have been an ideal situation."
