Juan Martin del Potro says he is delighted to see Novak Djokovic return to the top of the game and hopes that Novak continues to make tennis history.
“I believe in him,” Del Potro said.
“I know he has everything to win the first position in the world again. But I also know what he has been through to get into this position again.
“He had frustration with the injury and at the beginning of the year he came to every tournament and lost early. That is not normal for a player like him because I have been in that situation too.
“But now I am happy to see him in the first positions, to be winning Grand Slams and I am so proud of what he is doing again.
“Hopefully he can still make history in this sport because I love him. For his team as well, it is amazing. It is good for the tennis world.”
