Tennis legends Roger Federer and Novak Djokovic have both made millions from their careers on the court, but the Swiss has also shown his business nous away from the game

Roger Federer has turned his sporting success into financial triumph with a shrewd investment that dwarfs his tennis earnings. The Swiss legend's 3% stake in On Running has ballooned to an astonishing £277m ($360m).

The ten-time Australian Open has also impacted the life of photographer Valentin Hennequin, who looks distinctively like Djokovic. The Frenchman himself has admitted that he shares the similar ‘long face and strong chin’ look as the tennis superstar, and has now opened up on how his life has changed due to his appearance.
