Sinner was the first of them to make a breakthrough announcing himself as a mere teenager to the world. The Italian has since been overtaken by both in ways as Alcaraz is a Grand Slam champion and Rune is an ATP Master's 1000 champion.
Sinner is yet to win a trophy that big win but he's won several in his career so far. He actually defeated Alcaraz in a final before and played a few close matches high-stakes matches. It's a budding rivalry and just being part of this new wave of tennis superstars makes him very happy.
Everyone can see that the next generation is coming closer. Me, Carlos, Rune, Tsitsipas, Zverev, Medvedev. We are all very young. And so many other players are coming. It’s exciting to see others winning tournaments. Everyone is different and has different personalities and ways to play. It’s fun to be part of it.
The rise of the younger generation is certainly more fun for them than for the veteran players like Djokovic. The Serbian still reigns supreme most of the time but he will see himself slowly replaced by them in the next few years.
Sinner and Rune recently played Holger Rune in Monte-Carlo with the Dane denying the Italian his first win over him. It was a very emotional match that featured a chilly handshake with Sinner barely looking at Rune. He refused to comment on it after but stated now that he doesn't really have problems with any other guys on the tour.
I have zero problems with any of the other guys on tour, which is very important to me. I talk with everyone and have good relations with everyone. But I more go out and do my job and go back to my team and my friends.
