Jannik Sinner and Roger Federer sadly never met on the ATP Tour, but the pair would undoubtedly have played out a thrilling match on the court.

Federer helped ‘change tennis’, with his stunning career involving 20 Grand Slam titles and 103 ATP titles in total.

And Sinner is now on tallies of four and 20 respectively, having just clinched his maiden Wimbledon title in London.

Sinner winning Wimbledon is good for tennis, and means he and Carlos Alcaraz have combined to win each of the last seven Grand Slams.

Novak Djokovic represents the most recent champion outside of the duo, having previously dominated men’s tennis alongside Rafael Nadal and Federer.

And another former player has now discussed what a meeting between current world number one Sinner and former world number one Federer could look like.

John Isner said on the Nothing Major Show: “What a dream match-up prime Federer vs Sinner would be right now.

“With Fed dicing the second serve return, serve volleying as well. I like Fed, the legend. But that would be a dream match-up.”

Isner’s fellow former professional and fellow American Steve Johnson then commented: “I like Fed in that!”

John Isner says what Jannik Sinner does better than any other ATP player

Sinner has maintained his spot atop the ATP rankings following his Wimbledon success, where he really was in formidable form.

Fierce rival Alcaraz was defeated in the final at SW19, after the Italian knocked out the likes of Djokovic and Ben Shelton.

Analysing his latest efforts, Isner noted of Sinner: “I think a lot of credit needs to go to his coach Darren Cahill. That dude can coach.

“He admitted that something that they did work on a lot was going forward, coming in to the net more and trying to finish points at the net when they first started working.

“Two or three years ago when they first started doing it he didn’t look as comfortable. But he looked pretty comfortable [here].

“Maybe it’s not the favourite part of his game but he looks pretty comfortable going forward, he has improved so much since he started working with Cahill.

“We also talked about how good he is from the back of the court, especially in that match against Ben, when they essentially got into a baseline game and neutral ball rallies, Ben didn’t really have any chance.

“Ben is playing great from the baseline and Carlos even said during the match he was saying ‘he is much better than me on the baseline, he is playing much better than me’.

“I mean Sinner right now from the back of the court, you have to say, there is nobody better in the world. That is the reason why he is number one in the world.

“It’s him, Novak and Carlos, the three best players from the back of the court, but I think Sinner might be separating himself a little bit.”

Intriguingly, the world number one and his coach had previously decided to part ways at the end of the season.

But Cahill may continue working with Sinner, with the potential reversal of his decision certain to work wonders for the player.
