Frank Lampard has been named Chelsea's new head coach to replace Maurizio Sarri, returning to the club where he spent 13 years as a player.
The legendary midfielder, who won 11 major honors during his playing days at Stamford Bridge, takes over from Sarri after his return to Serie A with Juventus in his native Italy.
Lampard, 41, has just one year of managerial experience, gained at Derby County, but returns to the Blues on a three-year contract.
"It gives us great pleasure to welcome Frank back to Chelsea as head coach," Chelsea director Marina Granovskaia said.
"Frank possesses fantastic knowledge and understanding of the club and last season, he demonstrated he is one of the most talented young coaches in the game."
Lampard guided Derby to the Championship playoffs last season, earning praise for his style of play, only to suffer a 2-1 loss to Aston Villa in May's final.
The Rams granted the Premier League outfit permission to speak to Lampard last week and excused their manager from the first two days of preseason training to avoid a long-running saga.
Chelsea reportedly has paid £4million (approx. $5 million) in compensation to secure new leadership of a team that won the Europa League and finished third in the top flight last term.
Eden Hazard has since left and a two-window transfer embargo is set to force the London club to rely more heavily on its academy.
Lampard scored a club record 211 goals for Chelsea, and only three players have made more than his 648 appearances for the club.
His first competitive match in charge is Aug. 11 at Manchester United in Premier League play, with the UEFA Super Cup against Liverpool to follow three days later.
Derby, which is expected to turn to Phillip Cocu, announced that assistant Jody Morris and coach Chris Jones have followed Lampard to Chelsea.
