Mike Tyson appeared on the latest episode of Patrick Mouratoglou's podcast and the former World Champion discussed in particular Novak Djokovic.
Tyson spoke of his appreciation for his personality and mental strength and that he is his favourite player.
"I am very proud to see someone in the family who understands how things don't always go our way," said Tyson as reported by Super Tennis.
"Because life is like this, it's about learning to handle all kinds of situations. Now Djokovic is my favorite tennis player. If he's fine, I really enjoy watching him play games. It's amazing how he came back from injury and beat champions like Rafael Nadal and Roger Federer.
"Djokovic is a real fighter. Tennis changed my life. He has broadened my horizons and I am grateful to be involved in this sport."
