Chelsea have appointed former midfielder Frank Lampard as their manager on a three-year deal.
Lampard, 41, has left Championship side Derby County to take over at a club where he spent 13 years as a player. He succeeds Maurizio Sarri, who left Stamford Bridge in June to take charge of Italian champions Juventus.
Lampard led Derby to the Championship play-off final, where they lost to Aston Villa, in his first season as a manager. The former England international made 648 Chelsea appearances, winning 11 major trophies with them.
He takes over with Chelsea under a transfer embargo after the club were given a two-window transfer ban by world governing body Fifa - a decision they are appealing against at the Court of Arbitration for Sport.
