Vettel has conquered all before him this season, winning six of the eight races thus far, a performance that has seen him open an 87-point gap on Webber and McLaren's Jenson Button.
Webber admits that the place he finds himself in is a strange one.
"It is astonishing to be a little bit disappointed sitting second in the Drivers' Championship," he told the Daily Mail.
"It almost certainly hasn't gone completely as I would have liked but it is a fine line isn't it?
"Seb is obviously on a phenomenal run, which has made it solid for all the rest of us. There is only one guy that is really wrapped with his period up to now and that is Seb."
Despite Vettel's superior showing, Webber is still confident of clipping the German's wings, starting at this weekend's British GP where Webber triumphed last time out.
"He (Vettel) can be caught," insisted the resolute Australian.
"But he can also go on a roll again after he is caught. For somebody to outscore him by 80 points will be a phenomenal effort. So you have got to keep boxing and hang in there. Someone has got to get on a roll with some victories themselves."
Webber's future at Red Bull has been the subject of much discussion, with the 34-year-old's contract failing at the end of the season and a host of drivers connected to his position.
However, he isn't too worried that he doesn't yet have a deal in place for next year.
"Red Bull have been great and they are very keen to keep me, no query about it," said Webber.
"We are talking but there is no real importance from both sides. Timing is critical in anything in life. At the moment I am still getting some great results and I'm very, very close to getting some extraordinary results again," he added.
