After being beaten in straights sets by Swiss star Roger Federer in the final of the Dubai Duty Free Men's Open final on Saturday, Djokovic was left in awe of an astonishing performance from one of his arch-opponents – the other two being Rafael Nadal and Andy Murray.
"I have the biggest rivalries against these three guys and they are all different. After Rafa, I've played the most against Roger in some big matches.
"We always make each other play our best tennis. We require from each other the maximum focus and commitment and that's what raises the quality of the match," Djokovic said.
"That's why he's who he is. I managed to achieve a lot in my career, I was saying before that it is because of the matches against Roger and Rafa that I've managed to learn and understand mentally, physically, game-wise what I need to do to improve and to get myself to a high level and to win Grand Slams and be the best in the world. So that's also because of them," he added.
Djokovic had no answer to what Federer sent down in the final. "He has been like this in the important moments and big matches during his entire career. He hasn't been dropping his level too much. But again today was exceptional.
"I thought at least I'm going to get one good look at the rally or something like that, but he did a very good job," Djokovic said.
"While I did my best, I thought I tried to hang in there. Mentally I didn't want to let it go, and it was unfortunate in the end," he added.
