Novak Djokovic responded to critics this week who questioned if he was faking his hamstring injury suffered ahead of the Australian Open, saying the "narrative" around him seems to be "different compared to other players that have been going through similar situations." 

The 21-time Grand Slam champion fielded a number of questions during a press conference Monday about his hamstring injury after defeating Australia’s own Alex de Minaur in straight sets to reach the quarterfinals.

"Tonight, the way I played, the way I felt, gives me reason now to believe that I can go all the way," Djokovic said. "I mean, I always believe I can go all the way, in terms of my tennis but the way my leg felt before tonight wasn’t giving me too many hopes, so to say, for the entire tournament, to go all the way through. Tonight I feel that, so I feel positive about it."

But the Serbian tennis star has been criticized by some for his seemingly quick recovery, with some accusing him of "faking" his injury. 

"I leave the doubting to those people — let them doubt," he told Serbian media, via Sky Sports. "Only my injuries are questioned. When some other players are injured, then they are the victims, but when it is me, I am faking it. It is very interesting. I don't feel that I need to prove anything to anyone."

Djokovic said during his presser that it has been "exhausting" going through a number of treatments to try and get his leg back to where it was prior to the injury.

"I am not really interested at this point what people are thinking and saying. It is fun, it is interesting to see how the narrative surrounding me continues, (a) narrative that is different compared to other players that have been going through similar situations. But I am used to it and it just gives me extra strength and motivation. So I thank them for that."

Djokovic is pursing his 22nd Grand Slam title and is looking to extend his record at the Australian Open to 10.
