Mark Webber has contradicted Christian Horner's claim that he will retire if he leaves Red Bull.
Team boss Horner said recently that Australian Webber has "no desire" to switch to a rival camp as his current contract is set to expire at the end of 2011.
The 34-year-old has had a difficult start to the new season but told La Stampa in Turin that he is confident of a surge in form.
"When this championship ends my contract with Red Bull does as well," Webber told the Italian newspaper. "But I don't think it depends on the results; I want to win for me.
"We'll see," added Webber. "If the team doesn't want me any more, I will have to ask myself a question -- hang up my helmet or change teams?"
Last year I fought for the title and I want to do it again
He admitted he has "flaws" but said his teammate and reigning world champion Sebastian Vettel does too.
"I'm determined. Last year I fought for the title and I want to do it again."
As for Vettel, Webber answered: "Sebastian is very fast and he now has a good amount of experience. But he's not unbeatable.
"I prefer not to talk about his weaknesses, but we all have them," he insisted.
