The Sunday Times Rich List for young sportsmen in Britain is being published this weekend and we have a sneak peak at the top 10.
Unsurprisingly the list is dominated by footballers, although the top three are from different sports. We start at 10...
10. Eden Hazard & Amir Khan - £18m
Chelsea playmaker Hazard is joint 10th in the standings with boxer Khan, though Khan is likely to add to his wealth when he fights Canelo Alvarez next month. Hazard might be set for a new contract in the summer amid speculation he could be part of the Chelsea clear-out just a year after he was resoundingly the best player in the Premier League.
9. Samir Nasri - £22m
Nasri is one of three Manchester City players in this list and is only just returning from a long-term injury as he hopes to press for a place in France's squad ahead of this summer's European Championship on home soil.
7. Cesc Fabregas & Radamel Falcao - £29m
The Chelsea pair are level in seventh place, although Blues fans might need to be convinced they have earned their pay packet. Fabregas was central to Chelsea winning the Premier League title last year but, like his team-mates, he has endured a modest season this term. Striker Falcao has hardly played since arriving at Stamford Bridge last summer due to injury after a similarly troubled season at Manchester United.
6. David Silva - £31m
Another City player Silva has not had his best season at the Etihad Stadium, however, he has helped the Sky Blues reach the Champions league semi-finals for the first time.
5. Sergio Aguero - £33m
The Argentina striker is the highest ranking of three Manchester City player in the list and recently scored his 100th Premier League goal. The 27 year old is second behind Tottenham's Harry Kane in the Premier League goalscoring chart this season with 22.
4. Gareth Bale - £34m
Real Madrid's Bale is up to fourth on the list after a year in which he became the second-richest footballer. The Welshman earns around £15.6 millon a year at the Bernabeu in addition to contracts with Adidas, Sony and Electronic Arts. He is worth £34 million - a £13m increase from last year.
3. Rory McIlroy - £56m
McIlroy has enjoyed the biggest increase in wealth, earning an extra £18m to take him up to £56m in total and to third place in the list. The Northern Irishman earned almost 10m dollars in prize money, but it is off the course where he has made his real cash, with a long-standing deal with Nike and other endorsements with Omega, Bose, Upper Deck sports memorabilia and Electronic Arts being especially lucrative.
2. Andy and Jamie Murray - £58m
Tennis brothers Andy and Jamie Murray are in second place with a joint worth of £58m, though £57m of it is contributed by world number two Andy. The brothers teamed to help Great Britain win the Davis Cup last year.
1. Wayne Rooney - £82m
Rooney has amassed an £82m fortune which makes him the richest sportsman aged 30 or under, a rise of £10m from last year. The 30-year-old's wealth comes from a reported £300,000-a-week contract at United, which makes him the highest-paid player in the Barclays Premier League, as well as endorsements with global brands Nike and Samsung.
