Spa Francorchamps: Red Bull team boss Christian Horner hailed Sebastian Vettel's dominant display in Sunday's Belgian Grand Prix - and said it was a vital blow in their bid for a fourth consecutive title double.
The softly-spoken Englishman said the key moment was the 28-year-old German's opening lap passing move on Briton Lewis Hamilton's Mercedes.
"It was a matter of getting the first corner OK and then Sebastian grabbed the opportunity at Eau Rouge," said Horner.
"He had the momentum and he was able to go around Lewis and that was the decisive moment.
"There's still a long way to go, but it was a dominant performance from Seb, a perfect display by the team with pit stops and strategy.
"It was important for us to come back after the summer break and focus on the second half of the championship.
"We've seen Lewis was pretty strong in qualifying.
"This is not a track that suits us, but I'm delighted we got the win."
Horner refused to be drawn again on making any comment on who will partner Vettel next year when Australian Mark Webber leaves the team to go to sportscar racing with Porsche.
He said: "We are taking our time to think about this decision and we are under no pressure. It is not like the football transfer window or anything like that..."
Webber earlier told Australia's Channel 10 that a decision had been made that is "good for Australia" - a clear suggestion that Red Bull had chosen fellow-Australian Daniel Ricciardo to succeed him.
Vettel's win was the 31st of his career and lifted him 46 points clear of nearest rival two-time champion Spaniard Fernando Alonso of Ferrari in the title race.
In the teams' contest, Red Bull lead with 312ahead of Mercedes on 235.
