Rafael Nadal is undoubtedly one of the best athletes of all time, and his retirement represents the end of an era. The Spanish legend has squeezed his body beyond its limits in order to be able to extend his career as much as possible,

Nadal first signed with Nike at the age of 13, where he earned just $500,000 over five years. In 2008, he signed a 10-year contract extension worth over $10 million per year. In 2018, another five-year extension was signed for $10 million per year, according to Yahoo Sports.
