Frank Lampard says taking charge of Chelsea so early in his managerial career is his biggest challenge but he aims to be a success in much the same way that he was as a player at Stamford Bridge.
The 41-year-old won three Premier League titles, scoring 147 goals for Chelsea in the competition after moving from West Ham United in 2001.
Now, after only one season in management at Derby County, Lampard says the same work ethic he put in place to prove he was a good signing as a player for the Blues will be repeated as Chelsea's new head coach.
"I would say this is the biggest challenge of my career because my playing career is done, with some great memories and challenges along the way, and I always loved a challenge," he told Chelsea's official website.
"Coming here 19 years ago was a challenge because I remember driving home and listening to people on the radio questioning whether I should be here for £11million.
"I worked really hard to try to put that right as a player and now I’m in a position where I’m going to work really hard to be successful as a manager here."
'High expectations'
Lampard believes his experience of working under Chelsea managers such as Jose Mourinho, Guus Hiddink and Carlo Ancelotti will pay dividends.
"I'm aware what a job of this size means," he said. "I played here for long enough and the pressure was high.
"A club like Chelsea have high expectations and standards.
"In my playing career, I played with a lot of fantastic managers and that will hopefully stand me in good stead."
