Nadal is probably the most successful player from Big Three against new generation players. Also at the Mubadala World Tennis Championship, which he won, it was Stefanos Tsitsipas who defeated Novak Djokovic but later lost to Nadal.
During the 2019 season, Nadal lost to Tsitsipas once, he also lost to Dominic Thiem and the Spaniard was not successful against Alexander Zverev at the ATP Finals. But in the rest of the matches, Nadal won. He has also defeated Daniil Medvedev 3 times at the end of the year, 2 times in the final. About the new generation, Nadal said:
"It’s normal that there’s a buzz around them and it will get louder because we’re getting older every day and they’re getting better every day. Every year they’re improving. I think that they can win the biggest tournaments, like Medvedev, Tsitsipas and Thiem did this year. I think that Shapovalov is going to make a big step up this year and Sinner’s trajectory is incredible. They’re here to stay.
"We’re still around but the cycle of life is brutal and at some point that’s going to change, and sooner rather than later. There’s obviously some reason we have 20, 19 and 16 Grand Slams between us. We’ve been able to find a way to remain competitive and to keep being successful."
