"We spoke a lot about the mental aspect of the game, he has his feelings, just like any other person" - Holger Rune on Novak Djokovic 

Novak Djokovic has been known throughout his career for his mental fortitude. The World No. 1 often draws on his supreme mental reserves to prevail in difficult situations.

In an interview with Tennis Majors, rising star Holger Rune reminisced about the time he and Djokovic talked about the "mental aspect" of tennis. He revealed that the Serb told him to "be patient" during and that everything would be alright.

"We spoke a lot about the mental aspect of the game," Rune said. "He is also a human being, although he does not seem like a human when he plays sometimes. He has his feelings, just like any other person, but chooses to go the right way. Those are details, he told me to be patient and to take the long way, and that it is going to be all right."

The Danish teenager also spoke proudly of the time he earned the respect of Novak Djokovic after battling through cramps during their meeting at the 2021 US Open.

"After we played at the US Open, he was very surprised that I did not retire due to cramps. I definitely think that I earned his respect that night and I am very happy for that because it is not easy to get it – Novak is the best in the world, which goes hand in hand with certain standards," Rune continued.
