Flavio Cobolli reached the 2026 Roland-Garros semifinals on Wednesday and will meet childhood friend Matteo Arnaldi for a place in the final after a 4-6, 6-4, 6-3, 6-4 quarterfinal win over Felix Auger-Aliassime.
The result sets up an all-Italian semifinal between two players who grew up together and have never been this far at a Grand Slam. Cobolli’s victory put him one win from his maiden major final; Arnaldi advanced after Matteo Berrettini retired in the second set of their quarterfinal, leaving both men a single win short of the biggest match of their careers.
There are hard numbers behind how unusual the moment is: Cobolli and Arnaldi have met twice before and enter the semifinal with one win apiece, and neither had reached a major semifinal until now. Last year Cobolli beat Arnaldi here in the second round, in a four-set match, which gives the younger man a recent edge in their brief rivalry but nothing like the stakes they face this week.
Cobolli tried to keep the attention on the immediate task after his win. "I just want to think about the next match," he said, while acknowledging how close he feels: "But I know that I'm close, you know. Only two matches, but it's long way." He described the quarterfinal as different from earlier rounds, saying, "And I think I did something different from the other [matches]. Just tried to stay calm and play my tennis," and singled out the finish: "Today, in the last game, I think I played very good tennis with good serve and good first shot."
Those remarks underline both the confidence and the caution at the centre of Cobolli’s week. He has admitted to feeling nervous and to some superstitions around his Roland-Garros routine — details he treats as part of managing an unfamiliar pressure — but he pushes back against panic: "I think I never put pressure on myself." He prefers a simple motto for the run: "I like to live the moment like if I was a kid. Just with good, big passion, and a big smile."
Arnaldi arrives at the semifinal battle in a contrasting physical condition. He has logged 19 hours and 42 minutes on court to reach the last four and moved through his quarterfinal when Berrettini retired early. Still, he sounded upbeat. "I'm feeling pretty good, actually," he said, noting the uncertainty around his workload: "Obviously it was a question mark today, because I played two long matches in a row, but yesterday I didn't play tennis. I just came here, did some physio and some stuff in the gym." He added, "Today I was feeling actually pretty good. I can't complain," and framed the heavy minutes as part of what he loves: "I have been playing a lot, but at the same time, I'm happy to be on court and to spend time on court."")
The match will be shaped by familiarity as much as form. Cobolli and Arnaldi grew up together and know each other’s games inside out; that mutual knowledge will sharpen tactical choices and could make marginal differences decisive. Cobolli’s serving and first-strike tennis, which he praised after Auger-Aliassime, will be pitted against Arnaldi’s endurance and comfort after long hours on court.
Practical questions matter: Cobolli says he tries to remain in the moment and to avoid added pressure, while Arnaldi’s recent workload raises questions about freshness. Neither has been in this position before; the winner will reach a first Grand Slam final. That unresolved outcome is the clearest thing left to settle — one childhood friendship will pivot into a career-defining step, and the other will have to regroup and learn from the experience.
The match is scheduled next in the Roland-Garros semifinals; for fans and bettors the immediate question is simple and absolute: will Cobolli or Arnaldi take the single win that turns a mutual milestone into a first Grand Slam final?
