Despite heading into the final race of his F1 career, Mark Webber is adamant he's not disappointed to be saying goodbye.
Earlier this season, the Australian driver confirmed that this year would be his last in Formula One.
After 12 years in the sport and nine grands prix wins, the 37-year-old will be moving over to Porsche supercars for next season.
But despite saying farewell to what he has known, Webber says he's ready for his career finale.
"I feel ready for Brazil and am looking forward to a bit of a different chapter in the future," he said.
"There would be something wrong if I was disappointed to be finishing, because that's the reason I've made my decision, as a sportsman or woman that's why we all make those decisions: because in the end the fire is not quite what it was, and you've got to accept that.
"So the time is good for me, one to go and we'll put on a very good performance, I believe I can do that in Brazil.
"I'm happy I'm still driving pretty well, making my mark so to speak, but I've had my time. I've enjoyed it and achieved a few things, so let the guys do their thing in the future."
Webber's Formula One career will come to an end on one of his favourite circuits where he claimed the victory in 2009 and again in 2011.
"Interlagos is one of my favourite races, the atmosphere at the track is fantastic. The circuit sits in a bowl, giving it the feel of an amphitheatre.
"It's like Brands Hatch in the UK, where the crowd sits almost on top of the cars and it results in a fantastic atmosphere on race day. The race has been good to me because I've won it twice and I just enjoy being in Sao Paulo.
"The track is at a high altitude, so it's tough for the engines and the anti-clockwise direction makes it pretty physical for the drivers.
"There are more left-hand circuits at the back-end of the calendar than there used to be, so our necks are conditioned for them, but it's still a good workout."
