F1 2010 World Championship leader Mark Webber has vowed not to 'abuse' his current advantageous position atop the title standings and to 'leave no change on the table' over the upcoming final three grands prix of the campaign, insisting that he is all-too aware of the potential for things to 'go pear-shaped very fast'.

Heading into the unknown that is the inaugural Korean Grand Prix this weekend, the Red Bull Racing star holds a 14-point margin over his pursuing team-mate Sebastian Vettel and double F1 World Champion Fernando Alonso at Ferrari. However, over the last three races, the ultra-consistent Australian has found himself significantly out-scored by both the German and the Spaniard (tallying just 41 points to respectively 55 and 65), and the momentum is no longer on his side.

Determined to reverse that situation, the 34-year-old concedes that now is not the time to rest on his laurels and play a conservative percentage game - but rather the time to attack for glory, and to ascend the top step of the podium again for the first time since Hungary back in late July.

"We all have to go there (Korea), see the track and get on with the job - it's the same for everyone," he is quoted as having said by the BBC. "It makes no difference to me to be in the lead, and I can't think like that (about playing the percentages) - it won't be enough. I need to keep racing hard and going for victories. I need to win again, and I am very confident I can do that.

"Clearly, of course, if my rivals have a rough weekend it makes it a bit harder for them and it gives me a bit more scope, but I'm not looking to abuse that because it can all go pear-shaped very fast. Having a lead is great, but it only counts when you get to the last race and we haven't got there yet, have we?

"I may be in the lead, by a few points, but I don't think I am the favourite; I think we're all pretty even. It can change pretty quickly - in a good way or a bad way for me. It's on a knife edge, but I'm very relaxed. It's another race for me.

"I'll give nothing [away], leave no change on the table and do the best I can. The points will look after themselves. I just have to stay consistent and keep my head down. Reliability could still play a major role in the outcome. A lot of things can happen. Like I said, I need to be leading the championship at the last race, not now."
