I won't be threatened or intimidated by anyone and I've always been prepared to do what is necessary to defend my interests.

It's the engine. They should have never had that. The biggest mistake people have made... I say, "people," because it wasn't just me alone, was not insisting Mercedes supply Red Bull an engine. Because had they supplied the same engine as they had, you would have seen good racing, you would have seen Red Bull up there last year.

I have earned the money and changed the nappies!

I have no regrets about the amount of work I put into the sport. This is what I needed to do with my life.

Forget what others whisper in your ears. Most of that is pure rubbish that obstructs the view to what really is important. Always make your own decisions. That is what makes us human.

I suppose it's knowing when you've come up with an idea that works, when you've got it right, whatever it is.

Each new deal is another opportunity.
