Monaco manager Niko Kovac insists the club are keeping ahold of Benoit Badiashile.
Real Madrid and Manchester United have both been linked with the 19-year-old defender.
The latter has reportedly submitted an offer of €25m for Badiashile, but Kovac says he isn't going anywhere.
"Our aim is to take him to the next level," he told TF1. "If he plays a lot of matches with us in Ligue 1, which is a very good league, he will improve, that is certain.
"We do not want to sell him that is very clear. He will stay here this season. I think that this is the best solution for him. He has his club here, his family. He knows the environment."
