Klopp is one of the pioneers of today's high-intensity, full-court-press game. He's also a believer in horizontal hierarchies and teams without alpha-male stars - alpha males like Michael Ballack.

Kick off! puts the new millennium under a microscope with the help of Jürgen Klopp and Michael Ballack.
