That was a funny and very insightful interview from Rafael Nadal.
Here are the key points:
He said that his backhand and serve is doing well but he needs to improve his forehand a little bit more. He believes that if his forehand improves then his movement improves.
He still think that he is not the favorite because of his confidence.
He also said that he and Federer are old guys now. And even though he is old, he wants to play Tennis for a couple more years.
Finally, he believes part of the reason that Kyrgios is playing well right now is because of his big serve and he is young. He believes that because Kyrgios is young he doesn't have the pressure to do well thus he is playing well right now. However, once players and fans get to know him more, it will be harder for Kyrgios to play well and win.
I wish ESPN interview Nadal more because Nadal has a very interesting and insightful thoughts about Tennis and life.
