Sebastian Vettel wary of McLaren threat at Abu Dhabi Grand Prix
Red Bull's Sebastian Vettel admits he will be wary of McLaren's Jenson Button and Lewis Hamilton at Saturday's qualifying for the Abu Dhabi Grand Prix, saying they look "very competitive" and are the drivers to beat this weekend.
The Championship leader was 0.168 seconds quicker than Hamilton in second practice, while Button was third fastest ahead of Vettel's team-mate, Mark Webber.
Despite being fourth fastest, Webber admits he is frustrated after missing the end of the session with a mechanical problem that kept him consigned to the garage.
