The 1987 Wimbledon winner Pat Cash spoke about what makes Roger Federer and Rafael Nadal so special and unique. The Australian said: "Both have unique tennis games that have made them successful in the past and continue to do so as long as they remain fresh.
We have to remember that neither had serious injuries in 2016. In fact, Federer was clever and decided to take his time and get a niggling knee 100 percent right. Nadal did the same with his wrist. Both came back fully fit. The men’s circuit is a long one so players have very little time to get fully fit after a long year."
Darren Cahill added: "The game has changed in the last 20 years, becoming more physical in all aspects. Federer and Nadal are not the only players to prove that playing career best tennis into your 30s is very possible.
Better training, more education in protecting an athletes body, increased diet and supplement knowledge, and bigger support teams all add up to smarter, fitter, stronger and faster athletes. But that takes time and more athletes are now investing in time away from the court with physical training at an early age.
It pays dividends down the road." Stefanos Tsitsipas was asked if his win over Novak Djokovic in the Shanghai Masters quarter-finals was the best he has ever had in his career. The Greek replied: "It's the best comeback that I have ever had probably.
I would say also Federer's comeback in the Australian Open wasn't easy. I lose the first set against one of the best tennis players in the world and managed to win three consecutive sets after that. Same today but with less sets, two sets, which was quite difficult for me to pull out.
It was a very difficult victory mentally to -- I wasn't really thinking that long term that I have to win two sets. It just went step by step. It happened. I broke him, I won the set, I stayed there, broke him again, eventually I got the win at the end. Yeah, I wasn't really thinking too much of the future, and I think that helped a lot."
