Will Roger Federer continue to contribute to lifting tennis' standards? While he lost at the finals in Wimbledon this year to Novak Djokovic, he was clearly the better player. He made more mistakes, no doubt, but had the tenacity of a winner. There's no doubt, he'll remain as the greatest tennis player of all time for a long time more.

1. He's won 17 grand slams. More than anyone else, in history.

2. He's got flair, more so than most and is an all round player.

3. He's the reason everyone has improved their game.

4. At 32, he's the oldest tennis player now.

5. At 32, he almost won the 2014 Wimbledon.

6. At 32, his fighting spirit was incredible.

7. Even though everyone's game is getting better, he's not slacking off. 

8. He doesn't grunt. AT ALL.

9. He never loses his temper.

10. He keeps 100% focus on the game. Not on the crowd.

11. He hardly challenges calls. They are usually against him, but it's wrong most of the time.

12. He's making the younglings run around. An old man making you look like a fool on court.

13. He kept up to Tiger Woods' record and has already beaten him.

14. He doesn't have a coach.

15. He was using an old racket based on old technology up till this year.

16. He is humble in victory and graceful in defeat.
