The Reds sit second in the table, six points adrift of a Chelsea side who have strung together 11 straight wins.
Klopp told Sky Sports News: “There is no perfect system in world football, but when they go on like this they are the deserved champions, nobody could have a doubt about this.
“I am pretty sure that until now Chelsea are maybe the team that have had the most luck with injuries. We lost Phil (Coutinho) and Daniel (Sturridge) and Danny Ings in difficult moments when you really could use them.
“If it’s Hazard and Costa at Chelsea, is it the same afterwards?”
