Frank Lampard promised to keep Chelsea competitive at the top of the Premier League after his return to the club as manager on a three-year deal was confirmed on Thursday. Lampard won 13 trophies in 13 years and became Chelsea's all-time leading marksmen with 211 goals from midfield during a decorated playing career at Stamford Bridge. However, the former England midfielder has just one season of managerial experience having led Derby County to the Championship play-off final in May, when they were beaten by Aston Villa.
