Jannik Sinner's coach reveals world No1 broke his strict diet after heartbreaking French Open final loss to Wimbledon rival Carlos Alcaraz

Jannik Sinner's coach Darren Cahill has revealed the star broke his strict diet as the world No1 sought to cope with his heartbreaking loss in the French Open final last month.

The Italian, who is one of the favourites for the men's title at Wimbledon, had looked on course to dethrone defending champion Carlos Alcaraz to win the French Open last month.

Sinner had three championship points on the Alcaraz serve when leading 5-3 in the fourth set, but the Spaniard battled back to hold serve and then break, before forcing the match into a fifth.

Alcaraz would ultimately prevail in a final set tie break to claim a 4-6, 6-7, 6-4, 7-6, 7-6 victory in one of the greatest Grand Slam finals.

Having missed out in heartbreaking fashion on the chance to win a third straight Grand Slam, after US and Australian Open success, Sinner broke his strict diet to cope with the defeat.

Speaking on ESPN's Wimbledon coverage, Sinner's coach Cahill revealed the star took a glass jar filled with sweets from the player's lounge in the aftermath.

A photo of Sinner posted on social media also showed the world No1 leaving the venue with the jar, with Cahill revealing how it helped him to quickly process the defeat.

'I must say, about half an hour afterwards, he went and did the press,' he began. 

'We were walking to transport. We had this big bus where we all sit in and for the players they have this candy jar that you can take a couple of candies [from] as you walk out of Roland Garros. He took the whole jar.

'He grabbed the glass jar, had the candies, he'd been on a strict diet for two weeks and that was it. The diet was out the window.

'In the car, he was handing candies out to everyone.

'He was laughing, he was giggling. He moved on pretty quickly and it'll be interesting to see how he moves on here because this will be the big test.'

Cahill added that Sinner's awareness of his rivalry with Alcaraz could last for the next decade of more, with the duo aged 23 and 22 respectively, helped him to process the French Open final defeat.

The match had been their first meeting in a Grand Slam final and the duo would meet again in the Wimbledon showpiece if they live up to their seedings at SW19.

'He knows he's got 10 or 12 years at the top of the game if he continues to work the way he's working,' Cahill added.

'He knows he's going to have a lot more chances against Carlos Alcaraz in finals. They'll play a lot of big matches and he'll get his wins.

'The fact also that, had he won that tournament, we'd be competing here for the Sinner slam. He would have had three in a row. 

'He knows he's around the mark, he's improving all the time on grass.'

Sinner opened his Wimbledon campaign with a straight sets victory over fellow Italian Luca Nardi on Tuesday.

The top seed will face Australia's Aleksandar Vukic in the second round on Thursday.
