The greatness of Roger Federer's legacy in tennis started to get bigger year after year at the beginning of his career and the Swiss player felt it immediately. 'I was starting to be compared with other great athletes', Federer said.

'Maybe the first time I won the Laureus Award. When you get thrown into the greats like Tiger and Rossi and Shoemaker and everybody. And then that story came more and more, especially in the states, about Tiger (Woods). People would say who's dominating more and so forth.

And of course with the success I've had, the continued success, it's helped me to kind of go outside of tennis and some ways go outside of sports. You know, it's been very interesting and enjoyable for me actually to get away from the whole tennis thing all the time.' Federer also spoke about how he feel towards tennis featuring best of five matches only in Grand Slams by 2019.

'We would love to battle it out for five sets and make a big spectacle for all of us. Then at the same time we're happy to play best of three. If you look at an entire season and an entire career you avoid injuries here and there.

I think for the TVs it's just easier to set up. You don't have. To block a time for five hours and then tune out the last six minutes of last year's finals. That would be tragic too. It's easier if it's this way, it seems.

It's a bit of a dilemma both ways. I guess we're trying it this way and see how to goes. But I think by having this system now more cities and countries.' ALSO READ: 'Roger Federer should never play on clay again' - Andy Roddick
