Andre Agassi is a legend of the tennis world, winning eight Grand Slams and reaching No.1 in the world.
However, he has revealed a rather strange superstition from his playing days.
The now 45-year-old has revealed that he played most of his career without wearing any underwear.
“One superstition I had I found myself having by sheer luck — or unluck — but I went out to play the first round of the French Open against a really tough opponent who was playing some of the best clay court tennis in the world at the time," Agassi said in a video posted on his social media account.
“I realised when I was in the locker room getting ready that I’d forgotten my underwear. My coach wanted to lend me his and I was like ‘sorry man I’d rather go commando than wear yours.’
“So I played the first round so well I proceeded to not wear underwear the rest of the tournament and I won the tournament so I proceeded to not wear underwear the rest of my career.”
