Novak Djokovic: Boxing legend Mike Tyson snubs Rafael Nadal and Roger Federer

All three tennis stars are competing in the US Open, the final Grand Slam of the year.

The trio are all expected to progress to the final stages with Djokovic having won the last Grand Slam at Wimbledon earlier this year.

Each have a unique playing style, with Federer’s silky attributes helping him to 20 major titles.

Nadal’s brutal left-handed power has earned him 17 Grand Slams while Djokovic’s gritty, never-say-die attitude has led him to plenty of success.

“My favourite player of all time is Serena Williams, she’s the best of all time.”

Djokovic got the better of Federer in the Cincinnati Open final recently to enhance his ambition for the US Open.

And Annabel Croft has questioned where Federer’s confidence has gone, despite his opening round victory over Yoshihito Nishioka.
