Mark Webber says that for the moment the is just a normal weekend – although he concedes that will change as his final start approaches.

“I think on Sunday it will be a little bit different,” Webber said Thursday. “But it still feels like a normal race at the moment, so looking forward to Sunday in many ways, in terms of obviously pushing for a good result, but also I’m ready to stop and looking forward to the extended winter that I’ll have, and the new challenges around the corner. Getting out of the car Sunday, there will be a few things that will be for the last obviously in terms of , but I’m pretty relaxed at the moment and looking forward to the race.”

Webber admits that he’ll miss driving in at the most historic circuits.

“There are certain situations in Formula One that are super rewarding,” he said. “Obviously driving the car on the limit at certain venues is still very satisfying, no question about it. You’ve got , , Monte Carlo, come qualifying day and even racing, at certain circuits it’s very challenging and rewarding. So I’ll miss some of that. But I’m on a little bit of a slippery slope now, in terms of … you’ve got to be careful not to test it too much in terms of performance, and what you used to be able to do.

“I still think I’m driving well, but I don’t want to be around not driving well. So it’s inevitable that you’re going to miss certain parts — for sure, the adrenaline and working with people like Adrian Newey. Stuff like that you don’t get to do that often, obviously. That’ll be something I’ll miss a bit. But there comes a time when you’ve got to let go, and I’ll still have good adrenaline next year, obviously, with Porsche and that’ll be a good balance.”
