West Ham have signed Olympiakos left-back Arthur Masuaku for a fee of £6.2million, the club announced on Monday afternoon.

The Hammers announced on their official website that the 22-year-0ld has put pen to paper on a four-year contract after agreeing terms.

Masuaku makes a switch from Greece to England and will go straight into Slaven Bilic’s squad ahead of their Premier League opener against Chelsea next Monday.

Here is the club announcing their new signing on their official Twitter account.

Hammers’ manager Bilic had admitted it had been a “priority” for the team to secure a left-back signing in time for the opening weekend of the league season.

The Croatian had been publicly chasing a left-back for some time following first-choice left-back Aaron Cresswell being ruled out for up to four months with a knee injury.

Football Insider revealed on Sunday that the Hammers had sealed the double signing of left-back Masuaku and forward Andre Ayew following a breakthrough in talks.

Masuaku arrives in England having won back-to-back titles with the Greek club, including 12 appearances in the Champions League, but the Frenchman is now looking forward to playing alongside Dimitri Payet.

“It’s a big honour for me to be part of this Club,” Masuaku told the club’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.”
