Kemen swaps Newcastle for Lyon after signing four-year deal

Lyon said they had agreed to pay an initial fee of 750,000 euros ($848,625) for the 19-year-old Frenchman, in a statement on the club's website (http://www.olweb.fr/).

Newcastle are entitled to a percentage of any fee if the French club sell Kemen on in the future.

"Officially a Lyon player, really very happy to sign for this great club," Kemen said on Twitter on Monday night.

Newcastle signed Kemen from Ligue 2 side Metz in 2013 but he never played for the senior side.
