West Ham United have signed Arthur Masuaku from Olympiacos on a four-year contract.
The left-back has become the fifth player to join the Hammers this summer following the arrivals of Sofiane Feghouli, Ashley Fletcher, Manuel Lanzini and Havard Nordtveit.
The 22-year-old defender won two top-flight titles with Olympiacos during his two years at the Greek outfit, and also has Champions League experience having featured in 12 games.
"It's a big honour for me to be part of this club," Masuaku told West Ham's official website. "I was speaking with my agent about some opportunities, but when he told me about West Ham and also the coach, I didn't think twice, so in my mind, it was West Ham.
"Now, to be able to play with players like Dimitri Payet, I was thinking on the way here, it's going to be crazy! I can't wait to play with him and also all the rest of the team.
"For me, the Premier League is the biggest league in the world. When I was 18, my target was to come here, so now I am here, I have to prove myself to the fans and to the team so that I can play for this big club."
Masuaku, who is believed to have cost in the region of £1m, will wear the number 26 shirt. He will provide cover for Aaron Cresswell, who faces a lengthy spell on the sidelines with a knee injury.
