Forget the gold medals, the championships, and the undefeated seasons. Even sports stars, as they grew up, had the usual problems that all children around the world have. Michael Jordan, one of the greatest basketball players of all time, was very clumsy when he was young. Muhammad Ali's boxing career started when he accidentally entered a gym, looking for his stolen bicycle. The famous Lionel Messi stopped growing at the age of 11. These and many other true stories can be found in this wonderfully illustrated book.
