Rafael Nadal says the tour's non-stop schedule is exhausting him and there are days when he sees playing tennis as a job, rather than a sport. The Spaniard added that all his playing years have taken a toll on him and that even with the shortening of the calendar this year, the season will still be too long.

"It's my ninth year on the tour, and its completely the same feeling every year," Nadal told reporters. "You don't have the chance to stop, never. I think for that situation we have a shorter career. So having a different model of ranking, of competition, I think we can have longer career, no? I [am] almost 25, but seems like I am playing for 100 years here on the tour. I didn't spend a weekend at home since the week of Davis Cup before Indian Wells. That's too much. Tennis is a very demanding sport mentally and physically. I won Roland Garros five times, but next Monday I am practicing on Queen's. So that's makes the career shorter for everybody.

"We have four Grand Slams, we have nine Masters 1000, and the year is 12 months. I know that they're gonna reduce two week but, seriously, is not enough. [We are not ] gonna have these changes for my generation, but hopefully for the next generations to have a better sports life. Because I think you need two months, two months and a half of rest at the end of the season. You have to practice. I never able to practice and to try to improve the things during the off-season, and that's something I think terrible....Sometimes it's like work. And, in my opinion, tennis is not work. It's passion."
