Andre Agassi reveals how to determine the GOAT between Federer, Nadal, Djokovic

The Career Grand Slam owner Andre Agassi had a chance to play against or coach three legendary players, Roger Federer, Novak Djokovic and Rafael Nadal. However, he can't make GOAT predictions yet.

Praising three great rivals, Agassi said they are the best on each surface, respectively, proposing they have to play against each other on all three surfaces numerous times to determine who is the greatest.

"I think if you took the three best to talk about - Roger, Rafa & Novak - it is different to say who has the best career and when somebody is playing at their best, who is the best. We have the best on fast grass courts with Roger, we have the best on clay with Rafa, and the best on hard courts with Novak. There are multiple surfaces, they can play with each other a hundred times, and I will give you the answer.

I wasn't helping Novak for me; that's why I stopped. My reasons were because I believed that it's best for tennis if somehow he could get the best out of himself and then getting to know him & his family; I had a desire to help. My goal is to help you, but if I am in your way or stopping your process or interfering with your process, then it's best I sort of step out of your way.

But I can't necessarily subscribe to the choices that you are making. So there is a delicate balancing act, and we just far too often found ourselves agreeing to disagree, and that is ok too. There's no judgment in it," Andre Agassi said.
