Former World no.1 Andre Agassi has revealed two names who can challenge the Big Four group of Roger Federer, Rafael Nadal, Novak Djokovic & Andy Murray.

These four names have almost dominated the entire tennis world for over a decade or so. In addition to that, 36 years young Roger Federer is maintaining his supremacy & just few days back he became the oldest World number one in ATP History.

But according to American retired professional tennis player, Nick Kyrgios and Alexander Zverev have the capability to challenge these big names but wondered if they will be able to do it or not!

"There is a big difference between who has the talent to succeed the Big Four at the top of the game now and who can actually do it," Agassi told Tennis365. "There is an intangible factor that means you just don't know how a player will develop.







"Nick Kyrgios has a talent that is potentially unparalleled in the tennis world, but how much would you bet on him? Alex Zverev, that guy has a big game and he seems professional and focused, but there is so much that goes into the psyche of being the best versus trying to get there.

"At the moment, we are talking about talent, but you just can't say where they will take it."

Agassi also took an example of great Pete Sampras who won 64 career-titles with a impressive winning percentage of (77.43%). Agassi revealed how he judged Pete when he was only 17 & felt sorry for him by looking at his lazy & thoughtless practicing. But we all know what Pete achieved later!

"If you take Pete Sampras as an example, I watched him practice when he was 17 and I hadn't seen him since he was a kid playing 12 and under tennis," Agassi explained. "I see him at a professional tournament and I am like ranked three in the world and I feel sorry for him.

"I looked at him and thought this guy is not going to get anywhere. I feel so bad for him. He is not going to amount to anything. I mean, he can't hit a backhand, he looks so lazy and thoughtless out there practising and then he rolled over his arm, his mind went somewhere – and look what he achieved.

"You just don't know who can do it, when it happens. It's a trampoline affect and some guys bounce on it and then you can't stop them. Others you think are going to make it and they just fade. It's that extra factor that you just can't see that makes all the difference."

Federer, Nadal, Djokovic & Muray have 51-combined Grand Slams Titles, which is just a massive number to be outbreak by anyone in the future.





Swiss star is just brilliant with his form right now while Nadal & Djokovic are trying their best to gain their form back. Double-Olympic Champion Murray is struggling to achieve his full-fitness & is yet to appear for any major tournament after his hip-injury, happened at Wimbledon last year.

Nick Kyrgios and Alexander Zverev are certainly the two big guns but they are still not able to put any major challenge for the big four, certainly Roger Federer, who won another title at Rotterdam by defeating G. Dimitrov quite easily.
