Kylian Mbappe is a "phenomenon" but should stay at Monaco for another season as he will get regular first-team football with the Ligue 1 champions, according to Valere Germain.

Mbappe is a reported target for elite European clubs including Real Madrid and Paris Saint-Germain after hitting 15 league goals and impressing in the Champions League in a breakthrough season, with a world-record fee mooted for the 18-year-old.

But Germain – who left Monaco for Marseille this month – suggested the Stade Louis II may be the best place for Mbappe, who made his France debut against Luxembourg in March.

"If he stays in Monaco, it may be the right choice because he will continue to play and grow in this club," Germain told French radio station RMC. 

"After that he will probably have the chance to go to a big club this summer, it can also be good. So it's up to him to see if he feels ready to go, but he still has a lot of talent to succeed right now in a very, very big club."
