Sun and Ye have the world's best fan

If you're impressing the best, you must be doing something right.

The Chinese swim team's successful showing at the London Olympics didn't escape the attention of Michael Phelps. Phelps grabbed four more gold medals - the 100m butterfly, 200 IM, 4x200 free relay and 4x100 medley relay - in London to bring his record haul to 18.

He's retired now that the Games are over but said he's relieved to see new stars popping up.
