"I'm a completely normal boy from the Black Forest," said Jürgen Klopp when he took over as coach at Liverpool FC in 2015. He had barely arrived at the "Reds" and was a fan favorite. He was already popular as captain of the SV Glatten youth team, as a player and coach in Mainz, and then as a strategist at BVB, where his playing philosophy turned previously unknown players into world stars and the club into German champions twice in a row. "I like it when things go wrong," he once said. Where will he go wrong in the future?
