Rory McIlroy may earn more than Beckham

Rory McIlroy could easily become the highest-earning UK sportsman of all time, experts believe. Nigel Currie, director of sports marketing agency Brand Rapport, said: "He has the potential to do what Roger Federer, Michael Schumacher and Tiger Woods have done.

If he was to dominate golf, like he could do, for a number of years, he could get up towards the one billion-dollar mark. Lennox Lewis and David Beckham are the highest-earning sports stars from the UK so far, but McIlroy could easily pass them."
