Bernie Ecclestone is not worried that Red Bull's success will ultimate drive owner Dietrich Mateschitz out of Formula One.
Mateschitz and his Red Bull Racing team has dominated the sport in recent years, winning four consecutive Drivers' and Constructors' titles.
The team's success has raised some concerns that Mateschitz may find it all a bit boring and unchallenging.
Ecclestone, though, is confident the Austrian's enchancement with F1 will continue.
"I do not think," the F1 supremo said in an interview with Gazzetta dello Sport.
"The attitude is different because Dieter Mateschitz is a fighter who likes racing and enjoys seeing his cars win.
"With the economic benefit that has accumulated with so much success, Red Bull in the end will spend in the next seasons much more than a Williams or Force India.
"Where else could he find for the same price worldwide coverage so extensive and prestigious for his brand as what F1 offers?"
