Schwartzman explains why Alcaraz and Sinner might not reach 20 Grand Slam titles

Diego Schwartzman is stepping back into the tennis world, this time as the coach of a team in the newly launched professional league, INTENNSE.

Although Schwartzman retired from playing in 2025, he hasn’t stepped away from the game entirely. He’s remained active behind the scenes since then.

“There are different things that have changed now,” Schwartzman said. “The technology and information you have for each player is incredible now.”

“That was one of my favourite things when I used to play. Now, it’s even better than before.”

Schwartzman shares thoughts on Carlos Alcaraz and Jannik Sinner’s Grand Slam prospects

While Carlos Alcaraz already has three Grand Slam titles and Jannik Sinner added his first at last year’s Australian Open, reaching double digits isn’t easy. Schwartzman believes that while it’s possible, it might be too soon to predict such dominance.

“I don’t think so,” Schwartzman said. “It was going to be really difficult [for them] because when Rafa and Roger got their numbers over 20 you already had Novak Djokovic there.”

With most players only playing until their mid-30s, he suggests this era won’t produce another wave of record-breaking totals.

Sinner currently leads Alcaraz by two titles and holds a slight lead in their head-to-head record at five wins to four. Their rivalry is likely to define this era of men’s tennis.

The ATP schedule resumes with Indian Wells starting on March 6th, where both players will continue their chase for more titles against Daniil Medvedev (No.4) and Andrey Rublev (No.5).

Diego Schwartzman talks about what he wants to achieve with INTENNSE

Schwartzman will get the chance to build his own team in INTENNSE, going up against other ex-pros like Bob and Mike Bryan. He spoke about how this new chapter has come at the right time for him, especially after staying connected to the sport even after retiring.

“Partnering with INTENNSE gives me the opportunity to begin an exciting new chapter. Even though I retired from playing professionally last year, tennis still plays a big part in my life,” he said.

INTENNSE has introduced some new rules that set it apart from traditional tennis, something Schwartzman finds intriguing. The league is looking to appeal more to younger fans by changing how matches are played and presented.

“At the same time, tennis needs to become more welcoming, modern and exciting for younger generations,” he added. “With dynamic formats and creative storytelling that live alongside traditional tennis, not replacing it.”
