Schalke have signed highly rated France under-20 midfielder Amine Harit from Nantes in a deal reportedly worth up to €10 million.
The Bundesliga club say the 20-year-old Harit has signed a four-year deal.
Schalke coach Domenico Tedesco said in a statement: "Amine is a technically experienced player with strong dribbling skills who is also good in defense. He often looks for offensive solutions and can therefore make the difference."
Kicker reported Schalke is initially paying €8m for Harit, a fee which could rise with bonus payments.
Harit played in 30 league games for Nantes last season, his first with the senior side after coming through the youth ranks.
He won the Under-19 European Championship with France last year, when he was named among the players of the tournament.
