Mark Webber says he isn't considering that the 2013 F1 season could be his last, with the Australian stating that he is eager to keep racing 'as long as I feel good'.

The Red Bull man is the oldest driver on the grid this season after the retirement of Michael Schumacher although both Jenson Button and Fernando Alonso have started more races than the 36-year-old.

Webber is currently on a rolling one-year deal with the defending champions but he insisted that his position as F1's elder statesman didn't make him think it was getting close to the time for him to call it a day.

"I am the oldest but I am not the most experienced," he told The Sun. "Jenson Button has done the most races! It means absolutely jack s***. If Michael Schumacher was still on the grid, then how would that make me feel any different?

"I still feel 25. I know I am not but I feel young. I don't feel as though I am getting tired when driving the car. I feel good. I don't see this as my last year in Formula One. I have signed one-year contracts for the last four-years here even when I am fighting for the world championship."

Speculation about Webber's future has only increased thanks to various comments from Red Bull advisor Helmut Marko, but Webber himself said he was paying little attention to what the Austrian had to say.

"Of course I was not impressed with his comments but he has an agenda and I am not part of that," he said. "I was never a Red Bull Junior driver. We are all entitled to our opinions."
