Lionel Messi signed a new contract last week that will make him the highest-paid soccer player in the world at $27 million per year.
Going into the 2014 World Cup at age 26, Messi is already considered one of the best players ever and is already making more than $40 million with endorsements.
Despite that wealth and advertising exposure, he's is one of the most private people in the sport.
He drives a $200,000 car and lives in a nice house, but there may not be a more unknowable athlete in the world than Messi.
