Novak Djokovic: 'It's hard to stop, I understand Andy Murray'

regrets not having stopped to play when his hip injury was sort of telling him to. In a press conference reflected on the concept of keep playing despite you are not at the 100% of your physical abilities.

Its hard to stop, the 31-year-old recognized. We all have our individual choices that we make that have certain consequences, whether theyre positive or negative. For him, I understand why he said that.

I also had those kind of particular situations, kind of circumstances where I was questioning why Ive played so much or whether I should have played differently. At least in my case, I try not to have any regrets.

I think everything really happens for a reason. I just have to accept it, embrace it. In his case, hes really unfortunate to go through things that he went through in the last two years, the way it seems hes going to end his career this year.

This is really sad for all of us. We talked about it. Its sad to see him go that way, that is not on his terms. Injuries are the greatest obstacle that an athlete can have. Asked if he watched any of Murrays match, Djokovic replied: Yeah, of course.

I think everyone watched it. After two sets, I think no one expected him to really come back, considering how he feels. He showed once again his amazing champion spirit, why hes such a fighter, why hes so respected and appreciated around the tennis world, and sports world in general.

You could see everything that he is in that match yesterday. Unfortunately, ended up him losing. He can be proud of what he showcased. ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
