Matteo Arnaldi vs Flavio Cobolli 5 June 2026 Prediction

Italian fans likely have mixed feelings about their country’s performance at Roland Garros. On one hand, Sinner left Paris early. On the other hand, the French Open semifinal will feature an all-Italian matchup. On Court Philippe-Chatrier, Arnaldi and Cobolli will play for a place in the final. Last year, Flavio beat Matteo on the Paris clay fairly comfortably in four sets. Can he do it again?

Surface speed: 4/10

Arnaldi

It seemed as if Arnaldi might not return to his previous level. He dropped from the top 30 to outside the top 200. However, his career is now restarting quickly. Before the French Open, few expected him to go beyond the second round. Instead, he is once again playing some of the best tennis of his career.

Matteo’s counterattacking game does not always have enough power, but he tries to use his technical forehand to hit deep toward the baseline. With good endurance and strong court coverage, he can stay competitive in long rallies. However, his return numbers in Paris have not been especially strong: he has converted only 38% of break points and won only 24% of return games.

This spring, Arnaldi has won 68% of his clay-court matches, going 13-6, but he has faced top-20 opposition only once. Across his career, he has lost 7 of 13 clay matches against top-20 players.

Cobolli

Cobolli will become the seventh Italian player since 1973 to enter the world’s top 10 next week. His strong run at this Roland Garros is not surprising. It is not only about a relatively manageable draw before the quarterfinals. Last summer, he already confirmed his level by reaching the quarterfinals at Wimbledon.

Against Auger-Aliassime, Flavio once again showed his best qualities. He won thanks to excellent footwork and controlled many rallies with his strong forehand. He also played very well in tense moments, winning 10 of 14 points at 30-30 in games. That gave him the first top-10 Grand Slam win of his career and should add confidence before the biggest match of his career.

Cobolli has looked much better in Paris after disappointing results in Rome and Hamburg, winning 74% of his matches on European clay this spring, going 14-5. At Roland Garros, he has never lost to a lower-ranked opponent: 7 matches, 7 wins.

Tournament Form

• Arnaldi has reached the semifinals in Paris through difficult matches and strong determination. Only against Berrettini did he spend limited time on court, as Berrettini retired while trailing 7-5, 5-2. Against Griekspoor (6-7, 6-3, 7-6, 6-3), Tsitsipas (7-6, 5-7, 6-3, 6-2), Collignon (6-4, 6-7, 5-7, 6-4, 7-6), and Tiafoe (7-6, 6-7, 3-6, 7-6, 6-4), he had to work much harder.
• Cobolli has had some difficult moments on his way to the French Open semifinals, but he has not dropped more than one set in any match. He beat Pellegrino (6-4, 7-6, 6-3), Wu (6-4, 6-4, 6-4), and Tien (6-2, 6-2, 6-3) in straight sets. Only against Svajda (6-2, 6-3, 6-7, 7-6) and Auger-Aliassime (4-6, 6-4, 6-4, 6-4) did he need four sets.

Matteo Arnaldi vs Flavio Cobolli Prediction: Cobolli -1.5 Sets Handicap at 1.82

Main prediction: Arnaldi has fought hard in every match, but will he have enough energy left for Cobolli? We do not think so. Matteo has spent a lot of energy on his way to the semifinals. More specifically, he has spent 7 hours and 35 minutes more on court in Paris than Flavio. Many of those sets were also mentally demanding because the margins were so small. Cobolli, meanwhile, finished his match against Auger-Aliassime in four fairly manageable sets. The Italian No. 2 has beaten every opponent in Paris with at least a two-set margin, including Arnaldi in the second round of last year’s Roland Garros (6-3, 6-3, 6-7, 6-1). We are backing Cobolli -1.5 sets at 1.82.

Total prediction: Arnaldi’s matches in Paris have produced many games, while Cobolli’s have generally been shorter. Which pattern should matter more here? We lean toward Cobolli’s. Given Matteo’s accumulated fatigue, he may struggle to resist his in-form compatriot for long. For Flavio, only the match against Svajda went over 40 games, and only narrowly at 43. His average match length is 34 games. It is also worth noting that last year’s meeting between the Italians on the Paris clay lasted exactly 40 games. Therefore, our pick is Under 40.5 games at 1.64.
