Jannik Sinner and Carlos Alcaraz could be even better tennis players than Roger Federer according to Patrick Mouratoglou.
Sinner and Alcaraz never got the opportunity to play against Federer, with the 20-time Grand Slam champion retiring from tennis before they really hit their peak.
The current top two players on the ATP Tour have dominated men’s tennis since the start of the 2024 season, with Sinner and Alcaraz winning every Grand Slam since then.
When discussing Sinner and Alcaraz’s dominance, Serena Williams’ former coach Mouratoglou claimed that they have a quality that even Federer did not possess.

Patrick Mouratoglou claims Jannik Sinner and Carlos Alcaraz have ‘no weaknesses’
Mouratoglou was asked about Sinner and Alcaraz when speaking to Spazio Tennis, as he spoke about the big differences between the two players, comparing the former to Rafael Nadal.
“I think that Jannik and Carlos are opposite personalities, so different,” said Mouratoglou. “Carlos needs to be happy on the court in order to play his tennis, to be creative. If he’s not happy, because he had too much tennis, he’s not excited anymore [then] he is a different player.
“Jannik, no. Jannik is incredible…he has something of Nadal in a way. He plays full every point, every single match from the 1st January to the 31st December.”

Mouratoglou was later asked if he thinks any players can challenge Sinner and Alcaraz’s dominance, which he suggested was unlikely at the moment.
The Frenchman claimed that Sinner and Alcaraz have ‘no weaknesses’, which Mouratoglou explained was not the case for the likes of Andre Agassi, Pete Sampras and Federer.
“Those two guys have something in common, they are very different, they have completely different game, completely different personalities, but they have something in common, they have zero weakness, zero,” said Mouratoglou.
“If my player would have to play against any of those I cannot give them a tactic, well I can but it is not a tactic that would be focussed on the weakness on any of the two guys, they don’t have any weaknesses.
“If you remember Agassi, Sampras for example, best two players in the world, had a lot of weaknesses. They had a lot of strengths, some of their shots were incredible, but they had a lot of weaknesses. Even Roger had some kind of weakness that Nadal could use against him, but in today’s world of tennis, those two guys have no weakness.
“So to have someone who can challenge those two guys in terms of mindset, in terms of having no weakness, in terms of having incredible strengths, in terms of being unreal athletes, incredibly strong mentally, the challenge is quite high yes.”
Can any of these four players stop Jannik Sinner winning the French Open this year?
Is there anyone else you think could be a threat to Sinner?
