Ray Wilkins has returned to Chelsea as the club's new assistant first-team coach following the departure of Steve Clarke to West Ham.
Former Chelsea midfielder Wilkins embarks on his second coaching spell with the club, having previously worked under former manager Gianluca Vialli.
The 52-year-old begins work immediately and steps into the role vacated by Clarke who resigned to team up with former Blues hero Gianfranco Zola, now in charge at West Ham.
Wilkins will work closely with new Chelsea manager Luiz Felipe Scolari, and returns to the game after losing his coaching position with the England Under-21 side last year following Peter Taylor's exit and Stuart Pearce's subsequent appointment as head coach.
He became Chelsea's youngest captain at the age of 18 and was the club's player of the year on two occasions before moving on to Manchester United in 1979 after making 198 appearances and hitting 34 goals.
He later played for clubs including AC Milan, Rangers and QPR, and won 84 England caps, before managing QPR and Fulham.
While working with Vialli, Wilkins helped Chelsea to win th FA Cup and Charity Shield in 2000.
Chelsea agreed undisclosed compensation with West Ham to allow Clarke to move to Upton Park, after the former Blues defender handed in a resignation letter to make his intentions known.
