Nadal and his quirks

Most players have compulsive quirks, if you know where to look. Rafael Nadal makes his easy to spot. On a changeover, he has to have his water bottles arranged in just the right way, and he drinks from each in a specified order.

"I don't know if it's superstition or not," Nadal said. "I always do it the same." Palm Beach Post

Much has been made of this - and honestly he seems totally obsessed with this kind of stuff! It is very entertaining to watch.
