Mark Webber knows it is up to him to convince Red Bull that he deserves to keep his seat with the team beyond the 2013 Formula 1 season.
Webber is on a rolling one-year contract with Red Bull but his position could be under threat by Toro Rosso duo Daniel Ricciardo and Jean-Eric Vergne, who are eager to move up to the senior team in 2014.
Team principal Christian Horner insists the Australian will keep his seat if he delivers in 2013 and Webber himself knows that he is the only one who can prove he deserves to be offered a new contract.
Webber is not fazed about the constant speculation about his future, insisting that it is part and parcel of being a Formula 1 driver.
"It comes with the territory when you are with a top team and at the back end of your career. The vultures have been on the branches for the last three or four years, that is the way it is," Webber told reporters at an Infiniti-hosted press conference in Melbourne on Wednesday.
"There will be a day where I stop and someone will drive that car. And maybe the car is not competitive anymore, so it won't be important. Let's see what happens."
At 36 Webber is the oldest driver on the grid and while he is not looking beyond 2013, the Australian has refused to rule out a move to another team.
"Never say never," he said. "For me to finish my career [at Red Bull] is quite likely but you never know. The phone might ring tomorrow with something else," he added.
"It is a funny old business F1... chopping and changing teams late on, I'm not sure. I admire Rubens Barrichello for that.
"I couldn't have done what Rubens did, going from having been at the top and then going down - I am not particularly keen on doing that."
