Liverpool were knocked out of the FA Cup on Tuesday night.
The Merseyside club suffered their third defeat in four games in all competitions.
Jurgen Klopp says he is not worried about Liverpool's form after they suffered their third defeat in four games in all competitions.
Chelsea thrashed the Premier League leaders 2-0 at Stamford Bridge, thanks to goals from Willian and ex-Everton midfielder Ross Barkley.
After their exit from the FA Cup on Tuesday night, Klopp, who was happy with his side's performance, believes defensive errors cost them a place in the quarter-finals of the competition.
"Losing 2-0 is not good, but in this case it's relatively easy to explain. We made two massive mistakes around the goals," he said.
"The performance tonight was completely different to the performance against Watford. Against Watford, it was really bad. Tonight, it was not bad.
"I liked the reaction. I liked the way we played. There was some good stuff.
"It was a super intense game. We made seven changes because we knew it would be intense. But I'm not concerned about momentum. It's football.
"We never thought that it would be an easy season, that it would be an easy period, that it would be an easy game tonight. Nothing. It was always difficult, but we did very well. We were just not good enough in decisive moments, and that's what we have to accept."
The German acknowledged that the Reds need to improve their defensive display if they are to return to winning ways.
"It went our way for so long because we defended outstanding," he said of Liverpool's season. "Usually, you don't get a lot of chances against us. Now, we have to admit that in the last three or four games we have conceded too many goals."
While speaking BBC Sport, Klopp said: "I would really like if you stop mentioning it (the Watford loss). But we deserved to lose because they scored twice and we made massive mistakes for both goals.
"After that it was a completely open game, we had three-four shots in a row in the first half and Sadio Mane was close to finishing but the intensity of the game is why we made some changes. We needed fresh legs and then it needs to settle a bit but conceding does not help. The boys reacted well, I liked it but the second goal is a problem and Chelsea defended physically well.
"We are not unlucky in these moments, we looked good and Adrian made a superb save initially before the first goal. We have to be ready in the moments. We played Chelsea and they play in counter-attacks and that is OK, in moments they struggled with us. A lot of parts of the performance I really liked. We know we have to improve, it is not about destiny, not about not clicking here or there, it is all about us and we have to take it in the right way. It is not the best three weeks of the whole season but it is a a chance to make it the best three weeks now and that is the plan.
"We are not interested in Atletico Madrid, it is all about Bournemouth. They are fighting with all they have and they did really well against Chelsea. Nobody has to feel sorry for us, we will win football games and that is what we want to do on Saturday."
