Marseille have signed midfielder Georges-Kevin N Koudou from Ligue 1 rivals Nantes.
The 20-year-old broke into the first team at Nantes in the 2013-14 season and became an integral part of the side last term as Michel Der Zakarian s men finished 14th in the table.
The length of N Koudou s deal has not been made public, although widespread reports in France suggest the midfielder has been handed a five-year contract.
N Koudou made 32 appearances in all competitions in 2014-15, scoring twice, and will now look to stake a claim for a place in a Marseille midfield that is reported to be set to lose Giannelli Imbula to Inter.
FC Nantes thanks GK and wishes him well for the rest of his career, said a brief statement on Nantes official website.
