A study by the London School of Marketing has named tennis player Roger Federer the world's most marketable sports star.
The list ranked 20 sportsmen and women according to their potential earnings and endorsements.
Federer was one of seven tennis players to feature on the list, with world number one Novak Djokovic the next-highest in seventh, while Serena Williams and Maria Sharapova were the only women included in the list.
Golfer Tiger Woods was second, despite the former world number one slipping out of the top 250 in the world rankings, while Rory McIlroy was one of just two Britons to feature, the other being Andy Murray.
A similar list compiled earlier this year named Canadian tennis player Eugenie Bouchard as the most marketable athlete, ahead of her first-round exits at the French Open and Wimbledon.
