Vettel, unbeaten at the Indian GP, has finished on top in nine races this season, and five of them have come in a row. Such is his supremacy that in Singapore he won by a huge 34-second margin.
While Webber might believe that it requires a "perfect everything" to outwit Vettel, Mercedes' Nico Rosberg insists he has the car to beat the fellow German.
So, can he be beaten at all? Webber, who finished second behind Vettel in Japan despite starting on pole, said for that to happen, everything needs to click.
"He's on a phenomenal run obviously and as you said his stats here in the last few years have been pretty strong. It needs a perfect weekend -- pole, perfect race, perfect strategy, perfect everything to obviously put him off the top step, so that's got to be the plan," Webber, who would be bidding adieu to F1 at the end of the season, said.
