LONDON, England - Mark Webber has dismissed any suggestion that he has replaced Michael Schumacher as F1's oldest driver and is speeding towards the paddock exit.With Schumacher now back in retirement Australian Webber, 37 in August, has become the oldest driver on the grid. Combined with his new contract for 2013 only, the situation has raised expectations that could be the Red Bull driver's swan-song season.NOTHING NEW"I don't see this as my last year in F1" Webber told Britain's The Sun newspaper. "I've signed one-year contracts for the last four years."Webber said it was arguable that he was the driver closest to the finish-line; Jenson Button has actually contested more grands prix."(But) it means absolutely jack shit. If Michael Schumacher were 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'm getting tired when driving the car. "I feel good."Do you think Webber is approaching retiring age? Email us or post a message in the Readers' Comments section below.
