Rafael Nadal pronounced himself "a lucky guy" after sweeping to a seventh straight title at the Monte Carlo Masters by dispatching fellow Spaniard David Ferrer 6-4, 7-5 on Sunday.

Lewis Hamilton hinted Friday that he could leave McLaren in search of more success if the British team cannot provide him with a car capable of winning multiple world championships.

The 26-year-old Briton, who won the title for McLaren in his second season in 2008, said in Shanghai that his loyalty to McLaren had "limits" and that he was keen to maximize his time in the sport.

McLaren and Ferrari may look to Mark Webber to help clip his teammate Sebastian Vettel's wings in this weekend's Chinese Grand Prix -- and end his runaway start to the 2011 world title race.
