Korean Grand Prix - second practice highlights
Sebastian Vettel and Mark Webber set the fastest times in second practice for the Korean Grand Prix at Yeongam.
World champion Vettel was just 0.032 seconds ahead of his Red Bull team-mate, with Fernando Alonso third, Jenson Button fourth and Lewis Hamilton eighth-quickest after failing to set a timed lap on the faster super-soft compound tyres.
Vettel lies just four points behind Alonso in the world championship standings heading into Sunday's Grand Prix, with five races of the season remaining.
