West Ham have completed the signing of Arthur Masuaku from Olympiacos.
The French full-back has joined the Hammers for a fee in the region of £1million and has penned a four-year contract.
Masuaku made more than 50 appearances for the Greek side after joining them from Valenciennes in 2014 and helped them claim back-to-back league titles.
“It’s a big honour for me to be part of this club,” the 22-year-old told the Premier League club’s official website.
“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.”
Slaven Bilic moved for Masuaku after first choice left-back Aaron Cresswell was ruled out for up to four months with a knee injury.
He is set to be followed to Upton Park by Andre Ayew, with the Ghanaian forward close to a £20m switch from Premier League rivals Swansea.
