Mark Webber satisfied with fourth despite Kers problems

Mark Webber is satisfied despite only securing fourth on the grid for Sunday's Candian Grand Prix.

The Australian qualified without a working Kers system on his Red Bull, after a problem with the unit had already meant he was unable to take part in the morning's final practice session.

Webber was three tenths of a second slower than team-mate Sebastian Vettel - who took yet another pole position.
