Former Grand Slam champion del Potro has climbed back into the Top 10 and won a Masters event since returning from three procedures on his left wrist, and says Djokovic can also get back to the top of the game.
“I also had a couple of injuries in the past. It's not easy. It's not something nice to suffer,” Del Potro said. “It's not nice to see that you're falling down in the rankings, that you're not feeling as good as you're used to feeling, because he's always been really fit. There are few players that can come back from injuries and be so good, be up in the rankings where they deserve to be.
"Djokovic is one of those players. Also [Andy] Murray did it, [Stan] Wawrinka. There are not many more players that are capable of coming back from injury."
The Argentine said he would like to see a Djokovic resurgence, which would also make the men's game more competitive.
"For me personally, I would like to see Djokovic come back in the place where he should be," he said. "Hopefully, he'll be able to do that because I really like him, I really support him. It will not only be good for him but it will be good for the tennis world so that we can see again another great player, so we can see him fighting up there for Grand Slams, fighting for the No. 1 with all the top players.
"We have great players. That will make the tennis even more entertaining.”
