Frank Lampard has returned to Chelsea as their new head coach on a three-year deal.
Lampard enjoyed a highly-successful 13-year spell as a player at Stamford Bridge, becoming the club’s record goalscorer and winning three Premier League titles and the Champions League.
The 41-year-old began his managerial career in impressive fashion, guiding Derby to the Championship play-off final in his first season at the helm.
