Diego Schwartzman, who retired from professional tennis in 2025, has expressed skepticism about Carlos Alcaraz and Jannik Sinner achieving 20 Grand Slam titles. Now coaching in the new INTENNSE league, he highlights the challenges posed by intense competition and career lengths. Schwartzman emphasizes how modern technology aids players but sees barriers to record-breaking success.
Diego Schwartzman, the former professional tennis player, has transitioned into coaching following his retirement in 2025. He now leads a team in the newly launched INTENNSE professional league, which introduces innovative rules to attract younger audiences. Speaking on his new role, Schwartzman noted, “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 added that the league aims to make the sport “more welcoming, modern and exciting for younger generations” through dynamic formats and creative storytelling that complement traditional tennis, rather than replace it. Regarding emerging stars Carlos Alcaraz and Jannik Sinner, Schwartzman offered a cautious perspective on their potential to amass 20 Grand Slam titles. Alcaraz has secured three major titles, while Sinner claimed his first at the previous year's Australian Open. Despite their rivalry—where Sinner holds a 5-4 head-to-head advantage and reportedly leads in total titles by two—Schwartzman believes such dominance is unlikely. “I don’t think so,” he 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.” He pointed out that most players retire in their mid-30s, limiting opportunities for another era of exceptional totals. Schwartzman also praised advancements in the sport, stating, “There are different things that have changed now. The technology and information you have for each player is incredible now.” He recalled enjoying such aspects during his playing career and noted they have improved further. The ATP tour continues with the Indian Wells tournament starting March 6, featuring Alcaraz and Sinner competing against players like Daniil Medvedev and Andrey Rublev.
