There has been a lot of changes in this year's Forbes list of wealthiest athletes in the world. Some lost their top positions, some didn't even make the list and a few came out on top out of nowhere. Like Matthew Stafford who grabbed the 10th place after signing the richest contract in NFL history.
Brazil's Neymar, who became the world's most expensive soccer player after his $260 million move from Barcelona to Paris St Germain last August, is fifth.
Shockingly there are no women even on the list 100 people list, with tennis icon Serena Williams (was 51st in 2017), the sole lady on last year's roster, having dropped out of the rankings after taking a baby break from the sport.
