Roger Federer is known as a demigod on court, with his light touch, fluid strokes and poetic movement. But besides his tennis, Roger has made fans by how he acts off court. He is humble and witty. One can watch his matches for ages, but what I find the most enjoyable is listening to him in press conferences. You never know what the Fedex Express is going to do or say next.
Note: these are just my Top 10 picks. If you happen to find an even better one, please feel free to post it in the comments!
