Angers coach Stephane Moulin admits they're prepared to sell Rayan Ait-Nouri.
The young defender is the subject of intense interest from Manchester United and Manchester City.
Moulin says the club already have his replacement ready.
“It is not certain but there are chances that he will leave so we sought to get ahead of it," he told RMC Sport.
“We have decided that if Rayan leaves, we have his successor in Souleyman Doumbia.
“For Rayan, I have rarely seen a boy with this talent, he is very ahead of the game. He was very well balanced and I think that he will find himself in a big club."
