Sebastian Vettel will not dominate rest of season says team-mate Mark Webber

Mark Webber has written off Red Bull team-mate Sebastian Vettel's chances of reasserting his dominance this season.

Reigning world champion Vettel began the campaign in runaway form, winning five of the first six grands prix, and finishing second in the other.

Since then, however, Vettel has only won one of the last five as McLaren and Ferrari have reeled in the 24-year-old German on the track, if not quite in the standings.

Remarkably, despite not winning a race this season, Webber remains Vettel's closest challenger, albeit 85 points adrift, with Lewis Hamilton 88 points down, Fernando Alonso 89 and Jenson Button 100.

As far as Webber is concerned the Australian, who celebrates his 35th birthday on Saturday, reckons Vettel's one-man demolition of the championship is done and dusted.

"In terms of having five, six or seven wins on the bounce, that's over," said Webber, ahead of this weekend's return to action with the Belgian Grand Prix at the Spa-Francorchamps circuit.

"That is not going to happen. I think it will be more spread out.

"It will be the same customers, the usual suspects, the normal guys winning, and I am looking at getting involved as well."

Webber has also told Vettel not to count his chickens just yet on clinching back-to-back championships despite his seemingly all-too-convincing cushion.

"No, not if Seb doesn't finish two races," added Webber.

"I wouldn't just rely on someone not dominating. There are eight races to go, Seb is in a great position but it is not completely comfortable yet."

It had been anticipated Webber's future with Red Bull would have been resolved over the summer break, with the Australian extending his contract for a further year into 2012.

However, that has not been the case, although he claims the matter is slowly drawing to a close.

"We're not far away," added Webber. "Decisions will be made shortly, so we should be pretty close to doing something."

Asked whether it was now a formality, Webber replied; "It will be cheeky for me to say yes.

"My decision has to be taken into account, although the team's decision is pretty clear.

"Obviously (owner) Dietrich (Mateschitz) has been great, as have all the boys and everyone at the team. All will become clear shortly."
