Italian Jannik Sinner said on Sunday he had experienced "a few sleepless nights" since his historic French Open final loss to Carlos Alcaraz.

World number one Jannik Sinner wants to use the Halle Open as a chance to bounce back from sleepless nights after his agonising loss to rival Carlos Alcaraz in the French Open final this month.

At five hours and 29 minutes it was the longest final at Roland Garros, smashing the previous record set by Sweden's Mats Wilander when he beat Guillermo Vilas in 1982.

Jannik Sinner said he would try to "delete" the memory of his five-set loss to Carlos Alcaraz in the Roland Garros final on Sunday, after the world number one passed up three championship points as the Spaniard roared back to claim victory.

Carlos Alcaraz saved three championship points as he produced an astonishing fightback from two sets down to beat Jannik Sinner in a French Open final for the ages on Sunday.

Jannik Sinner said it "doesn't get any bigger" than facing Carlos Alcaraz in the French Open final, after ending Novak Djokovic's latest tilt at a record-breaking 25th Grand Slam title in the last four on Friday.

Novak Djokovic suggested he may well have bidden adieu to Roland Garros after the 38-year-old was defeated in the semifinals by Jannik Sinner on Friday.

"Jannik is in tremendous form, and he has been the best player for the last couple of years," said Djokovic.

Jannik Sinner booked himself a second consecutive semi-final appearance at Roland Garros on Wednesday with a typically ruthless straight-sets victory over unseeded Kazakh Alexander Bublik.

Women's second seed and former Roland Garros finalist Coco Gauff also targets a place in the last 32, after 18-year-old contender Mirra Andreeva cruised through.

Alcaraz fended off two set points late in the first set and then seized control in the tie-break before pulling away for a 7-6 (7/5), 6-1 win, his fourth in a row over world number one Sinner.

Jannik Sinner came through the first true test of his comeback from a doping ban with Tuesday's straight-sets win over Francisco Cerundolo which took the world number one into the Italian Open quarter-finals.

Sinner accepted a three-month ban in February following an agreement with the World Anti-Doping Agency, which challenged an independent tribunal's decision to clear him of wrongdoing after two positive tests for the anabolic agent clostebol.

Carlos Alcaraz said Sunday that the pressure to reclaim the world number one ranking from the suspended Jannik Sinner has had a negative impact on his form this season.

Sinner received a three-month ban agreed with the World Anti-Doping Agency (WADA) in February after "admitting "partial responsibility" for team mistakes.

Jannik Sinner accepted on Saturday a three-month ban from tennis after the world number one admitted team mistakes led to him twice testing positive for traces of banned substance clostebol last year.

"He has lost only four or five matches in the past year, so it's crazy. I know people say who's better out of us. They say Jannik is better or some say me. It's all discussion."
