AS Monaco have completed the signing of highly-rated Lyon forward Willem Geubbels for a reported €20m fee with a sell-on percentage clause.
The 16-year-old is viewed as one of the most exciting prospects in France and has signed a contract that will keep him at the Stade Louis II until 2021.
Geubbels made four appearances for Lyon last season, and became the all-time youngest player in Europa League history when he came on as a substitute away at Atalanta.
The 2017 French champions are understood to have beaten RB Leipzig to the signature of France U18 star, and the club was personally recommended to the teenager by the Monaco coach Leonardo Jardim and striker Radamel Falcao.
Geubbels told the club website: “I am very happy to sign for AS Monaco. It is a historic club that plays in the Champions’ League and competes every year in Ligue 1. The project of the club is ambitious and relies on the development of young players. I cannot wait to meet my new team-mates, to learn from them. I am ready and determined to help the team do great things”.
