Watch the full version of Sky Sports F1's exclusive interview with the legendary Ross Brawn.
Martin Brundle sat down with the former Ferrari technical director and Mercedes team boss at the recent Goodwood Festival of Speed, where Brawn's own 2009 title-winning car ran up the famous hill for the first time.
Nearly three years after his exit from Mercedes, the 61-year-old also gave his thoughts on the world champions' subsequent domination, and about the 'calmness' required at Ferrari for his other old team to return to the top.
"They need a quiet approach," said Brawn. "It's important that Ferrari still respect what they have to do, but they do it progressively and quietly.
"Because I think that was a great success in our period, that Jean Todt and Luca Montezemelo kept a lid over everything and enabled us to work on the engineering side and the racing side.
"So I think it's a quiet approach with the necessary planning and resource. They've got some very good people there -James Allison is excellent. If they give him the resources and give him the time and put the infrastructure around him, with great drivers, they'll get results."
Brawn also discusses whether he would be interested in one day writing F1's rules.
