Roger Federer always stood out for his sportsmanship and great class on the court and off the court with players, media and fans. Federer cares about it a lot. 'I make sure the image of tennis is set up the right way, which I think is important - and I think it is', Federer said.

'Obviously, I always try to be an example to children, be a role model. I think that is very important. So I think -- I hope I'm doing the right things, on and off the court. I'm trying to act very naturally. I'm just myself on the court.

Seems that people like it, so it's good.' Many people say that Federer has the perfect game. He is the player they most like to watch. What goes through his mind when he hears that? 'It's nice to hear. I've gotten many, many compliments throughout my career, so it's not really something new.' Comparing Sampras and Agassi, Federer added: 'I can only go as far as players.

I don't know them good enough personally, so that would be something strange for me to tell them how they are, their character is. I can only tell you how they are on the court. They both seem very respectful to the game and to their opponents.

Obviously, they have a very different game. I think we see both games, they're very dominant in what they do: Agassi from the baseline, and Pete at the net and with his serve, you know. So they have totally different qualities, but they had similar careers.

For me, Sampras' career is quite extraordinary. So it's hard to compare, you know, one to the other. I think that would be also wrong to do, but I think it's great they had such a fantastic rivalry throughout the years.

Obviously, as soon as Andre goes for me, also it's a pity that he goes because I wish I could play more of him.' ALSO READ: 'Roger Federer should never play on clay again' - Andy Roddick
