Singapore Grand Prix: Vettel and Webber 'surprised' by practice pace
Red Bull Racing's Sebastian Vettel and Mark Webber both say they are "surprised" after finishing second practice in Singapore a long way ahead of their nearest rivals.
Vettel was over a second clear of Mercedes' Nico Rosberg in third, while Webber, despite hitting the wall on his fastest lap, was sixth tenths off his team-mate and set the fastest time on the medium compound tyres.
Also giving their thoughts on Fridays' two practice sessions are Mercedes' Lewis Hamilton, Ferrari's Fernando Alonso and McLaren's Jenson Button.
