20. Gareth Bale ($36M)

Age: 27

Injuries limited the Welsh international to just 21 La Liga starts in the 2015/16 season, but he managed to score 19 times, much to the delight of Real Madrid, which paid a whopping $118 million to acquire him in 2013. Bale is also a standout fixture for sponsor Adidas, having inked a six-year contract in 2014 worth an estimated $35 million.
