The tennis world number two Rafael Nadal says his hunger for a second Olympic gold at next year's London Games is stronger than ever.
The French Open champion made the comments after playing fellow Spaniard David Ferrer in an exhibition match in China.
Nadal won gold at the Beijing Olympics in 2008 beating Chile's Fernando Gonzalez, and the 25-year-old says he's keen to represent his country again, in London.
