PARIS: Carlos Alcaraz promised a spectacular Roland Garros final against top seed Jannik Sinner after the reigning champion advanced past an injured Lorenzo Musetti in the last four on Friday.

The Spaniard was leading 4-6, 7-6 (7/3), 6-0, 2-0 after two hours and 25 minutes of play on Court Philippe Chatrier when eighth seed Musetti was forced to abandon with a thigh issue.

Second seed Alcaraz will defend his crown against world number one Sinner, after the Italian dashed Djokovic's latest tilt at a 25th Grand Slam with a straight-sets victory in Friday's second semi-final.

It will be the first time the pair meet in the final of a major.

"It's going to be a really great Sunday, I think, for the fans of tennis," the 22-year-old said.

"Jannik, he's the best tennis player right now. I mean, he's destroying every opponent through (to) the semi-final," he added of the three-time Grand Slam winner, who is yet to drop a set in the tournament.
