TEnnIS: World no.1 Rafael nadal has enjoyed one of the most successful seasons in tennis history but the Spaniard thinks winning the four Grand Slams in a single season is beyond him. nadal, top seed at the Shanghai Masters, won Wimbledon and the uS and French Opens this season, plus a string other titles over a blistering ten months. However, injury forced him out of the Australian Open quarter-finals. 'For me, winning the four titles is impossible,' said the 24-year-old yesterday. 'I will try to keep playing well and to try to win four titles next year. But it may not be the case they are all Grand Slams. That's impossible, I think.'
