CULTURE: Roger Federer and Rafael Nadal walk on water!

The world’s top two players, Rafael Nadal and Roger Federer, already two of the greatest champions in the history of tennis, took to a floating court in the Persian Gulf to promote this week’s 2011 ATP Qatar Open in Doha.

The tournament serves as an important warm-up for the Australian Open which starts in a few weeks.

“It’s a special Australian Open with me being the defending champion,” Federer told the press this week. “Obviously the focus is going to be on the two of us. Tennis is really going to be exciting down in Australia.”
