The 24-year-old, who has previously been linked with Wigan Athletic, is regarded as one of the brightest talents in Ligue 1.
"I want to play in England. Wigan were interested in me the last two seasons, but I wanted a big challenge and I was not ready for that," he told reporters in France.
"My agent is talking to various English clubs so things can move quickly. Everton could be great for me and they are a huge club in England. I will realise my dream playing for such a club."
