There is no doubt that there is plenty of money in the sporting world, with the number of sponsors and television opportunities rising every year, the elite stars of the worlds most popular sports are able to earn an incredible amount of money.
While money isn't at the heart of most athletes as they try to climb the ladder of success in their chosen sport, it certainly is a major bonus, with some athletes earning an unbelievable sum of money on a yearly basis.
Of course, not every athlete is able to earn huge sums of money, but for this list, we will be focusing on the richest sports stars of 2019 so far.
We kickstart this list with Kevin Durant, who is the 10th richest sports star in the world within 2019 according to Forbes, with the NBA star earning $65.4 million in earnings this year alone.
Durant could have probably earned even more had he accepted the Warriors extension deal, but instead, Durant opted to become a free agent and signed a deal with the Brooklyn Nets which was worth up to $164 million of the four-years he signed on for.
He also banks $35 million from sponsorships per year and has investments in various companies, including the popular Postmates which helps his net worth grow and grow.
Another basketball star who makes the list of richest sports stars in 2019 (proving how much finance is in the NBA currently), is Stephen Curry who is earning almost $80 million in earnings this year.
The charismatic NBA star signed the league's first $200 million contract back in 2017 and has had the league's top salary in the two year's following that, making him incredibly marketable as he works alongside Palm.
As well as that, he owns his own production company, Unanimous Media that actually has a deal in place with Sony Pictures, with their first movie, Breakthrough, being released earlier this year.
The legendary LeBron James comes in 8th as the richest sports star of 2019 as he earns $89 million in earnings, with the legendary NBA MVP being under a four-year contract with the Los Angeles Lakers which is worthy of $153 million.
James has the top endorsement portfolio in the NBA, bringing in plenty of money from his sponsorship deals as he remains one of the most popular athletes in the world.
Away from the court, his foundation opened up its first elementary school last year, with James set to invest $41 million in sending kids to college, while he and his partners also own 14 Blaze Pizza franchises.
Aaron Rodgers is set to net $89.3 million in 2019, with $9 million coming from endorsement deals with the rest being made up from his current contract deal, making him one of the highest-paid NFL stars in the league.
Rodgers has taken his finance and started to invest it elsewhere, in order to prepare him for life after the NFL, as he purchased a minority ownership stake in NBA side, Milwaukee Bucks.
As well as that, he launched a $50 million venture with Roth Capital, with Rodgers being a general partner as he continues to find ways to grow his wealth.
Russell Wilson is set to earn £89.5 million in earnings in 2019, with a large portion of that coming from his April 2019 move where the Seahawks signed him on a four-year contract extension for $140 million.
The deal made him the highest-paid player in the NFL currently, which is why he ranks so highly on this list, with the Seahawks clearly showing how much Wilson means to them by committing so much money to him.
One of the reasons the team values him so highly is likely because of the fact that he led them to their first, and currently their only, Super Bowl championship in the 2013-14 season, making him a legend there.
Roger Federer is not only an incredible tennis player, who is, in fact, the most successful in the history of the sport, but he is also one of the most well-respected professional athletes in all of sport.
Federer is set to earn $93 million this year in earnings, which is superb at this later stage of his career, and he recently signed a deal with Japanese apparel brand, Uniqlo on a 10-year deal worth $300 million.
Over the course of his career, Federer has earned an impressive $124 million in prize money, while he has also brought in $86 million in off-court earnings from the likes of Rolex.
In 2018 the streaming service, DAZN committed to an unbelievable $365 million deal to broadcast 11 of Canelo Alvarez's fights, which is one of the greatest deals in the history of boxing.
Canelo is a major draw for boxing, having only ever lost one fight out of his 55 career bouts, winning 35 times by knockout, with his fight against Gennady "GGG" Golovkin being the first U.S. boxing fights to draw over one million buys since Manny Pacquiao and Floyd Mayweather Jr.
With Canelo being a very confident talker and an athlete who can comfortably back things up inside the ring, he is easily marketable and desirable for sponsorship opportunities, which is why he is earning $94 million in earnings this year.
The Paris Saint-Germain star is earning $105 million in earnings throughout 2019, which is a massive amount of money, especially considering his age, with the Brazilian set to only increase his wealth throughout the years.
Neymar's current five-year deal with PSG is worth $350 million in salary alone for his time playing for the club, with the transfer that the French outfit paid ($263 million) being the highest in soccer history.
Neymar is also the second most popular athlete on social media currently, with more than 200 million followers on Twitter, Facebook, and Instagram combined, which is why he is able to land huge endorsement deals.
Considered to be one of the greatest soccer players of all-time, it is no surprise to see Christiano Ronaldo this high on the list, with the Portuguese star earning an incredible $109 million in earnings throughout 2019.
Ronaldo has had an unbelievable career in soccer and won everything there is to be one, whether that be in England with Manchester United, Spain with Real Madrid, or his new club Juventus.
Ronaldo is bringing in an impressive $65 million purely through his salary and winnings this year, while he gains $44 million through his various endorsement deals.
That's right, a top three of soccer players, with Lionel Messi taking the top spot as the richest sports star of 2019, which isn't a major surprise as he and Christiano Ronaldo are considered to be the two best players on earth right now.
Messi has broken all sorts of records throughout his career at F.C Barcelona and is considered to be the best player of all-time by a lot of critics, which is why he is able to earn an incredible $127 million in this year alone.
According to Forbes, Messi is bringing in $92 million from his salary and winnings alone, while the rest of the money ($35 million) comes from his endorsement deals, showing just how badly company's want to work with him.
