Vettel still the man to beat in China

But unpredictable season so far means it's anyone's Grand Prix

SHANGHAI - Germany's Sebastian Vettel will fancy his chances of giving Red Bull Renault back-to-back wins at the Chinese Grand Prix on Sunday as he sets his sights on becoming the circuit's first two-time champion.

The 22-year-old was the first to finish here in the rain last year. After claiming his maiden win of 2010 in Sepang, Malaysia, two weeks ago, another victory would put him at the top of the driver standings, where he trails Ferrari's Felipe Massa by two points.
