Rory McIlroy has been unveiled as Nike's new brand ambassador in Abu Dhabi, making him one of the highest paid sports stars in the world.
The exact detail of the sponsorship may never be revealed, but it has been reported to be worth around $100m (£62m) to $125m (£77m) over five years.
That could earn the County Down golfer around $50,000 (£31,000) a day.
