Nick Kyrgios opens up about heartbreaking US Open

Ahead of the Japan Open, Nick Kyrgios opened up about his heartbreaking US Open loss but thinks he can win a grand slam in the future.

Kyrgios defeated Daniil Medvedev at the US Open with many thinking he is a lock to make the final. The Australian certainly thoughts so too but neither he nor fans around the world thought he could lose to Karen Khachanov:

"I thought the US Open was a great chance - obviously, that one really, really hurt because I definitely thought that I was the favourite after I beat [Daniil] Medvedev."

He is still certain of future success believing himself capable of winning a grand slam. His next chance will come at home in Australia:

"Now I just have to wait until the Australian Open but I just want to keep my form, the way I'm playing, I want to keep that going. I'm doing all the right things so I definitely think I can win a Grand Slam, for sure."

He added:

"For a couple of years, I didn't even get past the third round - I wasn't training hard enough, I probably wasn't taking the sport seriously enough. Now, the last year and a half I've been training really, really hard. Grand Slams are all you really get remembered by. You can't just rock up to a Grand Slam and expect to win it. You have got to put the building blocks in and the foundations in place. I'm super excited to be here, that's for sure."
