Formula 1 still needs Bernie Ecclestone after its £3.3bn takeover, says former driver Sir Stirling Moss.
And Briton Moss, 86, believes that can only be good for F1.
"He is exceptionally important - thank goodness we've got him for three years," said Moss.
Ecclestone will be joined at the helm of the sport by new chairman Chase Carey, vice-chairman of 21st Century Fox.
Speaking to BBC Sport on Thursday, Ecclestone joked the pair were "dictators".
Carey added: "This is a great global sport and one where we're just going to keep trying to build on what Bernie's built over the last four decades.
"This is an evolution. We're going to work together. The best businesses are partnerships where people work together as a team."
Moss, who raced between 1951 and 1961 and has retained a keen involvement, says the development under Ecclestone has been exceptional.
"Motor racing now is really good, you look at the pits and they are all nicely organised, and everything works well," he added.
"He's done so much for the sport and brought it forward enormously. Look where we are now."
Ecclestone has had a strong grip on Formula 1 since becoming chief executive of the Formula One Constructors' Association (FOCA) in 1978.
His controlling nature has been advantage to the sport, according to Moss.
"As long as he controls it properly what does it matter? It's what you need. He's a dictator but he can get it done.
"It's an amazing thing to see a man like that. He can call anyone up in the world and they will stop what they are doing and speak to him. He's a very big man."
