Lyon have completed the signing of midfielder Pape Cheikh Diop from Celta Vigo on a five-year deal.
The Ligue 1 club's president Jean-Michel Aulas had confirmed on Saturday that a deal was agreed between the two sides and Diop underwent a medical a day later.
The Senegal-born 20-year-old has now completed his move to France for a reported initial €10million fee.
Diop, who has represented Spain at youth international level, featured 16 times for Celta in LaLiga last season, scoring once.
