Casper Ruud says the big three of Rafael Nadal, Novak Djokovic, and Roger Federer are 'all great guys' behind the scenes on the ATP Tour.
The big three have dominated tennis for a decade-and-a-half, winning an astonishing 58 Grand Slams between them.
That, though, has not affected their humility, according to Ruud, who has revealed to Beyond the Baseline podcast, what they are like towards the younger players on the ATP Tour.
"I think they're all great guys," Ruud said of Federer, Djokovic, and Nadal.
"I know Rafa the best obviously, but I've played against Roger and Novak in a match and they were nice to me both on the court and off the court after the match.
"When I've seen them they come up to me and say 'hi how you doing' and I think that's really nice.
"They have probably hundreds of thousands of people in their life they could say hi to and when they actually come to say hi to me, in the gym, that shows that they're great guys.
"The last time was Djokovic at the Australian Open he didn't have to come say hi to me in the gym when I was warming up but he still did and I thought it was nice.
"They are nice guys and know how to behave well and they've been in the game for a long time.
"Maybe they also have some experience of when they were growing up and maybe Sampras went to Roger when he was younger and said hi and then Roger thought that was a cool thing and I'm sure he knows it's a nice feeling for us young guys to be greeted by him.
"I know Rafa better and we say hi all the time. We see each other at tournaments and he sends me messages when I play matches and do well, he's the closest I am to, but the two others are just as nice."
