The Dutch winger had been linked with the Catalan side for over a year and has finally signed a deal.
Memphis Depay, 27-year-old winger has joined Barcelona on a free transfer after running down his contract at Lyon.
Goal.com reported that the attacker is the fourth player to join the Spanish side this summer, following Sergio Aguero and Eric Garcia, who were both signed after leaving Manchester City, and Emerson Royal.
Barca were linked last year and again in January but the winger has finally reunited with former Netherlands boss Ronald Koeman, penning a two-year deal.
The announcement comes days after Ronald Koeman said that a deal was in the works, telling reporters : “It’s not signed yet, but it’s almost there.”
The Netherlands international joined Lyon from Manchester United in 2017.
He scored 76 goals in 178 appearances in all competitions over his four years with the French side.
Depay and Koeman reunited
Depay worked with Koeman for almost two years while the 58-year-old was in charge of Netherlands.
Depay scored 11 times in the 18 matches he played under Koeman before the coach was lured to Barcelona last August
