The Spaniard has already won four major titles but is in awe of his rival's accomplishment of winning 24 of the biggest events in tennis.

Alcaraz said of starting his US Open campaign: "It is an act of brutality being totally honest. What I can say… I can speak just to myself. I am very happy with my daily work to have the opportunity to win these titles as much as possible.

"I am 21 years old and I have already won four [Grand Slams] but I am hoping it won’t stop here.

"A lot of people are saying that if I have already four how many I will be able to win in the future… but it won’t count much if you have won four now and that stops and you won’t evolve.

"My task is to keep growing and improving to win as many as possible because that’s my aim. It is what Djokovic has done during his whole career… he always wanted to keep improving when he played these kinds of tournaments, to give his best version.

"That’s what he has always achieved and that’s why a lot of people admire him. Let’s hope he won’t be able to continue winning more titles.

"Let’s wait and see but hopefully we will be able to continue with this path."

Alcaraz refused to get involved in the controversy surrounding Jannik Sinner's failed drug test and suggested there are details about the case that the public may not be aware of after the world number one was allowed to continue competing.

He said: "It is a very sensitive and serious issue. I think there is some info ‘behind’ that a lot of people don't know, and I include myself because I don’t know.

"It is very difficult to speak about it. He tested positive but there have been some reasons that we don’t know that allowed him to play. There is not much I can say about it.

"At the end, he was innocent, or they consider him innocent, therefore Jannik will play in the tournament and there is not much else to say and won’t be speaking too much else about it."
