Lampard has lost his first two games in the job.
But Lampard told BT Sport's Sport in Focus: “You don't know [about your abilities] until you start the job.
“It is easy to rely on my 21 years of playing, but it is different when you come to the other side.
“One thing I learnt a lot about myself was when you see something, or feel something, it is how you deal with it to improve.
“It is quite easy sometimes to coach, and things happen in training, but you have to wait for the right moment where you can have a moment of improvement, either individually or for the group.
“I am not trying to blow my own trumpet here because there are people who do it who are the best in the world.
“What I am more interested in is the detail behind the scenes, the moments one-on-one, sometimes off the pitch, and the moments which are crucial when you work with the team as a group and on how you want to play."
