Federer and Kaka go head-to-head!

When Roger Federer and Kaka got together a couple of days ago for a Gillette promotional event, neither superstar could resist putting on a show for the breathlessly excited crowd. Federer started showing off a bit of his football skills by kicking a ball around, before Kaka showed off some of his mad skills which left Federer shaking his head. Maybe next time they can go head-to-head in tennis? :P
