Button thinks good start is key to Singapore success

Jenson Button is determined to make a good start in Sunday's Singapore Grand Prix after qualifying in third position behind the Red Bulls of Sebastian Vettel and Mark Webber.

The 2009 world champion believes he may be advantaged by starting third as it is on the 'clean side' of the grid - with cars starting on the racing line theoretically able to obtain better grip off the start line.

Button believes he needs to have Sebastian Vettel "in his sights" after the start to have any chance of winning at Marina Bay.
