Chelsea boss Frank Lampard is confident of success with the Blues.

The ex-England midfielder, who replaced Maurizio Sarri, believes he can succeed as a manager like he did as a player — when he won three Premier League titles and the Champions League.

In a new book out now, 'The Boss — Chelsea managers from Ted Drake to Frank Lampard', Lampard said: “You wouldn't have dreamed the Chelsea job would come along after a year at Derby.

“Was it the right decision to take the job so early?

“It was a question posed at the time of my appointment — whether it was too early in my development as manager.

“But I didn't ask myself whether it was too early. I had confidence in my ability.

“But I understand why it was the first question.

“I had a wonderful playing career with Chelsea but that has nothing to do with my new role as manager.

“This is a challenge I had no fear of taking and have no fear of doing.

“My objective is simple — to be as successful as it is possible to be at Chelsea.

“If I don't, then that should not influence what I achieved in 13 years as a player.

“But my intention is to succeed as a manager the way I succeeded as a player."
