Webber predicts 'tight' battle for pole

With the Montreal circuit's characteristics not playing to the strengths of the RB6, many had expected Red Bull's main title rivals McLaren to seize the initiative.

But with Sebastian Vettel having been quickest in second practice, Webber is more optimistic about his own team's chances - as he predicts a close battle for supremacy.

"We thought McLaren might do more today, but it is early in the weekend," said Webber. "We are pretty happy with how the day went. I think we were pleasantly surprised with the pace, which is a good thing for us.

"We're going to have a tight fight tomorrow with everyone, but the car ran really well today and we will see how the weekend goes."

Webber was one of many drivers who suffered from tyre graining during the first practice sessions - something he hopes will decrease as the track rubbers in over the weekend.

"It is always the same in Montreal. The track is very tricky and we will see how it goes over the course of the weekend, but it is a normal thing for this surface in Montreal.

"The option is not great - in fact it is pretty poor for most people. It is not going the best at the moment, but should be okay for Sunday."
