Liberty Media's F1 takeover deal could lead to the departure of the sport's chief executive Bernie Ecclestone, the supremo has hinted.

Bernie Ecclestone has hinted he could walk away from Formula One following the sport's takeover by Liberty Media.

The US media conglomerate purchased the sport earlier this month, but supremo Ecclestone is tempted to leave his role.

Ecclestone confirmed he has been asked to stay on as chief executive of F1, but is unsure how the deal will play out.

"[The takeover] shouldn't make any difference," Ecclestone told Sky Sports ahead of the Singapore Grand Prix. "They've asked me to stay on in my position. 

"Chase [Carey] is going to be chairman, I've no idea what his ideas are, but it is difficult for him as he's sort of been thrown in the deep end a bit. So we'll see.

"The only thing I have to do is die and pay my tax. Short of that I don't have to do anything.

"There is going to be no problem with Chase, we will work together. He has got expertise that I haven't, we need to be in America, he knows America, he knows television and he can help us a lot. So I'm sure that is what is going to happen.

"At the moment I am still able to deliver. When I think I can't then I'll stop. 

"Thank God at the moment I don't quite need the money, I don't need a job and if by chance things aren't going the way I think would be the right way then I will disappear for sure."
