The defender moves across London to represent the Hammers, who are currently tied with Chelsea at the Premier League summit
West Ham United have completed the signing of Chelsea and France defender Kurt Zouma, the Hammers confirmed on Saturday.
Zouma, 26, was left out of the Blues' squad for the weekend clash against Liverpool as his move across London drew nearer.
And he has now been confirmed as the Hammers' latest arrival after signing a four-year deal at the club, leaving the door open for more transfer activity back at Stamford Bridge.
