Ross Brawn has underlined Sebastian Vettel's important contribution to Ferrari's resurgence this season.
Brawn still keeps an attentive eye on the Scuderia's affairs, not only as Formula 1's sporting manager but also as the former tech boss and strategist for the red squad during its Schumacher golden era.
Vettel has won two races so far this season and currently leads Lewis Hamilton in the Drivers' standings.
Following a spell of disappointing seasons marked by Fernando Alonso's inability to win the world championship, the House of Maranello saw its foundation rocked with several attempts at reorganization.
Last year, the team's new technical structure finally took hold, with Ferrari now bearing the fruit of its efforts.
"The last few years for Ferrari have not been easy," Brawn said last year.
"But I think the crucial thing for them is stability. There are really good people in the team, who need the right support and the right philosophy."
With stability now achieved, the team is building on its foundation and Brawn sees Vettel as a vital component of its success.
"What Sebastian is doing in the red car is great advertising for Formula 1," Brawn told Sport Bild.
"Most fans want to see a successful Ferrari team, and Sebastian is the key to it."
