Let's be realistic about that. I think Mercedes when it started the engine [development] didn't have a budget. It spent. And then lots of teams don't and can't. I mean Red Bull, for example, that won four world championships, didn't know the word "budget", and it's a case that it hadn't got the ability to have the engine that it should have had. Because somebody else [Mercedes] had the engine, wouldn't let them have it, because they didn't want competition.

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

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 think I would find it easier to talk with Nico [Rosenberg] than Lewis [Hamilton], as Lewis is into things that are very distant to me.

[Olympics] obviously, is not the easiest thing to do, and nobody makes any money out of. Yet, for the small amount of money they could [invest] in a Formula One race, they don't want to do it.

[Maurizio Arrivabene is quite a character] but only for himself and not for Formula One.

Take away Toto Wolff's Mercedes shirt and send Sebastian [Vettel] down a street - nobody would recognize him.
