Following his victory over Paul in the quarterfinals of the 2025 French Open, Alcaraz is set to face eighth seed Lorenzo Musetti in the semifinals of the tournament.
Musetti secured his place in the semifinals by defeating qualifier Yannick Hanfmann, lucky loser Daniel Elahi Galán, Mariano Navone, and 10th seed Holger Rune in the first four rounds. In the quarterfinals, he overcame 15th seed Frances Tiafoe to advance to the final four, where he will go up against Alcaraz.
Alcaraz and Musetti have met six times on the ATP Tour, with the former World No. 1 winning five of those match-ups. Their most recent clash was in the semifinals of the 2025 Italian Open, where Alcaraz won 6-3, 7-6(4). He then defeated Sinner in the final, securing his seventh Masters 1000 title and 19th overall career title.
Meanwhile, Sinner will face Djokovic in the other semifinal of the 2025 French Open. The Serb defeated Mackenzie McDonald and Corentin Moutet in the first two rounds, followed by a win against qualifier Filip Misolic. He then defeated Cameron Norrie in the fourth round to reach the quarterfinals.
In the quarterfinals, the 24-time Grand Slam champion eliminated third seed Zverev to advance to the semifinals, where he will compete against Sinner.
Djokovic and Sinner have faced each other eight times on the ATP Tour, with each player winning four matches. Their most recent match-up was in the final of the 2024 Shanghai Masters, where the three-time Grand Slam champion triumphed with a score of 7-6(4), 6-3, claiming his fourth Masters 1000 singles title.
