Spain's Wimbledon champion Rafael Nadal says he'd love to go to the football World Cup and watch his countrymen lift the trophy.
But after his brilliant three sets win over Tomas Berdych this morning, the world number one says he needs more treatment on his troublesome knees before the US hardcourt season, leading up to the US Open, the only grand slam title he's yet to win.
Nadal says football's his favourite sport, but he might not have time to make the long trip to South Africa.
