The German believes his side's hectic schedule over winter has denied them the chance to be a little closer to Antonio Conte's Blues in the race for the title.
Asked what was the lesson he learned during the Reds' below par run of form of late, Klopp said: "December-January.
"Not even Chelsea came through without no problems but they were able to play the same team all the time. They left the EFL Cup when, before it started?
"I don't remember them playing one game in that competition. 'Get rid of this.' I spoke to Antonio [Conte] for a long time at Anfield, maybe 25 minutes, and he mentioned it [the fixture schedule] but said they could play the same 13-14 players all the time.
"That is the big difference.
"In December we missed players and did not have the best schedule.
"We could have had two, three or four points more
"We are not used to being a top team, maybe we have to be. We are not clever like Chelsea who will be 2-0 up and just finish a game."
