Webber: Red Bull blown away in China

Webber finished in eighth position, two places behind team-mate Sebastian Vettel, as Red Bull was unable to be competitive in the difficult conditions.

The Australian admitted his team was simply not fast enough.

"We got blown away so it was a very difficult grand prix for us," Webber told the BBC. "We weren't quick enough, simple as that.

"They were changeable conditions but it's the same for everyone, and the car is very sensitive in these conditions if it is not going one way or the other for you. Interesting grand prix.

"We know (where we lose out in these conditions) and we have got to improve it."

Vettel, starting from pole, admitted the result was disappointing, although he reckons the points could be important later on.

"In the end to finish sixth can be quite important, but our main competitors finished ahead so that's not nice," Vettel told the BBC. "It was a very difficult race for us, both of us struggled quite a lot in certain conditions.

"Once we are in clean air our pace was decent, but you know, it is very on/off in these conditions and it is a lot just to maintain track position.

"We need to understand why we were not able, especially out of the restart, why we were not able to be there straight away. We were lacking a little bit of temperatures in the tyre."

The German, under investigation for his pitlane incident with Lewis Hamilton, said he did not understand the Briton's driving.

"I was in a similar track position as he was after the first stop and we found our way through the field," he said. "At the stop you were mentioning I was ahead, I don't know why he was keen to touch me.

"I thought hopefully I don't suffer a puncture after that, don't really understand because I was a bit ahead. He turned out to be a little bit faster on the track anyway so we need to see."
