The 22-time Grand Slam title winner, back on court this week after three months on the sidelines, battled well but eventually crumbled against the hard-working world number 11 from Australia.

The 22-time Grand Slam champion had not played a competitive match since January but eased past the 62nd-ranked Cobolli in 85 minutes to reach the second round.

Nadal's return a few weeks ahead of the French Open raises hopes the Spaniard will be able to compete in Paris, where he is a record 14-time winner.

Tennis superstar Rafael Nadal said Monday returning to action at the Barcelona Open is a "gift" and he wants to enjoy every moment of what he expects to be the last year of his career.

The 12th-ranked Greek, who will return to top 10 on Monday, also won the title in the principality in 2021 and 2022.

The 22-time Grand Slam winner has played just once, in an exhibition match, since he felt a hip injury flare-up during a quarter-final defeat by Jordan Thompson in Brisbane on the eve of the Australian Open.

Novak Djokovic admitted he was "not having a great season at all" after he was knocked out of the Monte Carlo Masters by Casper Ruud in the semi-finals.

Casper Ruud finally defeated Novak Djokovic at the sixth attempt on Saturday, setting up a Monte Carlo Masters title showdown with Stefanos Tsitsipas.

An inspired Stefanos Tsitsipas handed Jannik Sinner his second loss of the season on Saturday as the two-time champion reached the Monte Carlo Masters final 6-4, 3-6, 6-4.

Rafael Nadal will make his return to ATP competition for the first time since January when he plays Flavio Cobolli in the Barcelona Open next week.

Djokovic will take on either Casper Ruud of Norway or France's Ugo Humbert for a place in Sunday's final.

Rune beat Sinner in the semi-finals last year.

"First training... with the hope of being here these days before the start of the tournament. I'm here to see how it goes... with the desire to try to play," wrote Nadal on social media, alongside a picture of the Spaniard sitting courtside with his rackets.

World number one Novak Djokovic said his "feeling was great" as he flew past Roman Safiullin in straight sets at the Monte Carlo Masters on Tuesday, after third seed Carlos Alcaraz withdrew from the event due to injury.

Rafa Nadal's withdrawal from the Monte Carlo Masters has cast doubt over the 22-times Grand Slam champion's participation at the French Open, but Novak Djokovic said he is still hoping for a final chapter in their storied rivalry.

"Unfortunately I have to tell you that I am not going to be playing in Monte Carlo. My body simply won't allow me," said the battle-weary Spaniard on social media.

Jannik Sinner said he is enjoying every moment of his sensational start to the 2024 season after winning the Miami Open on Sunday for his third title of the year.

Italy's  Jannik Sinner destroyed defending champion Daniil Medvedev 6-1, 6-2 in just 69 minutes on Friday to reach the final of the ATP Miami Open, where he will take on Grigor Dimitrov.

Djokovic has had a poor start to the year by his standards.

Novak Djokovic and Goran Ivanisevic are to go their separate ways, the tennis world number one announced on Wednesday, ending a five-year association which yielded 12 Grand Slams.
