Daniel Ricciardo believes he's the perfect fit for Red Bull even in the midst of rumours that he physically won't fit into an Adrian Newey-designed cockpit.
Although there has been no official confirmation, the Toro Rosso driver is rumoured to be heading to Red Bull Racing next season where he will replace his retiring compatriot Mark Webber.
However, there has been some speculation that Ricciardo won't actually fit into one of Newey's cars, which are known for being compact.
"It's my hips," he laughingly told the Daily Telegraph.
"I've got wide hips. It's not my arse per se. I guess it's genetic. Even when I signed for Toro Rosso we had to do a few seat fits and they did some scans to make that particular part of the cockpit a bit wider, so that we're not sitting on the actual carbon fibre.
"But yeah, I've heard that Adrian does like to build small race cars. I can't do much about it. Even if I go on a massive diet my hip bones aren't going to change."
The 24-year-old, though, is quick to point out that at this stage it doesn't matter because an announcement of confirmation has yet to come.
"Until something is done I'm not getting too excited," he said. "Then if it doesn't happen I won't kill myself."
But should it happen, the Aussie concedes it won't be an easy task racing alongside three-time World Champion Sebastian Vettel. However, he reckons he's up to it.
"I am definitely aware that if I do get the opportunity to race alongside [Vettel], it is not going to be easy.
"But I would love to get the opportunity to prove to everyone that I have what it takes - and more than that, to know for myself that I can mix it with the big guys. If I can't, well, at least I can say I tried. But I believe I can."
