Rafael Nadal SNUBBED for Roger Federer and Novak Djokovic by boxing icon Mike Tyson

The former heavyweight champion is a huge tennis fan, along with his 9-year-old daughter Milan.

Tyson has been keeping an eye on the major tournaments this year, which Federer dominated at the start of 2018.

The Swiss star won the Australian Open and Rotterdam Open, before coming second at the Indian Wells Masters.

Since then, Rafael Nadal has overtaken the 36-year-old in the ATP rankings.

But Tyson has been more impressed by Federer, who he calls the greatest ever.

"It's fantastic that he plays at this level at this age," he told TennisChitChat.

"His record at the beginning of the year was impressive, unfortunately, he lost two matches in Indian Wells and Miami.

"And now he has stopped (for the clay season).

"A good decision, I think. He can afford it.

"He is the greatest of all time."

Tyson's daughter hit with Djokovic at the Indian Wells Masters last month.

And the Serb is another who the 51-year-old is impressed by.

"She is great," Tyson said about his daughter.

"She met Serena Williams, I was so proud of her.

"He [Djokovic] is my favourite at the moment.

"If he is okay, I really like to watch him."

"He played some good matches in Monaco now, it doesn't look so bad."
