“Nadal has 13 grand slam titles already, Roger Federer is on 17. When Roger broke the record of Pete Sampras on 14 we thought that would never be broken, but I don’t think that any more. I think Nadal will retire with more slams than Federer. I can see him winning three more French Opens – that would take him to 11. It sounds crazy, but he is that good,” said Goran Ivanisevic.
“Only Djokovic can beat him on clay, and he came really close this year at the French Open, but that experience might make it more difficult for him in the future,” he added. You have to put your body and mind through a lot to stay with Nadal on clay, and I’m not sure he will be able to do it again.”
“Nadal is the only player that can win all four grand slam tournaments in one year. He has won all of them in his career, and even though he says it is impossible, he is the one man who could do the calendar slam. If he stays fit, who knows? He could even reach 20 grand slam titles. It’s possible,” he added.
