Brawn enjoys Rosberg's first win
Mercedes team boss Ross Brawn is delighted at finally being able to uphold a promise he once made to Nico Rosberg.
For Brawn, Sunday's triumph in China was one of many victories he has been able to savour throughout a brilliant career that has seen him at Benetton, Ferrari and his own team for a year in 2009 prior to Mercedes' takeover.
Naturally, it still was of considerable significance, but more so for Rosberg who finally stood atop a podium for the first time in 111 grands prix and in his seventh season in Formula One.
The wait has been a long time coming for the 26-year-old German, so too for Mercedes after their return to the sport at the start of 2010 following a 55-year hiatus, bowing out in 1955 with the drivers' title courtesy of the legendary Juan Manuel Fangio.
"All wins are very special to be honest," said Brawn.
"But as someone reminded me, I was one year old when we (Mercedes) last won a race, so this is a very special victory.
"It's made all the sweeter because it is Nico's first, and I am really delighted.
"That's because I told him once it was my ambition to help him win his first race, and we've achieved it."
The question now is whether it was a one-off, or has Rosberg opened the floodgates to more success?
"He's pretty composed anyway, but it will be fascinating to watch, to see what this does with Nico, his approach," added Brawn.
"But I have to say he's very professional, so I don't expect a huge change, but certainly it will be a boost for him."
With Mercedes, it is all about the management of the tyres, a feat they achieved superbly in Shanghai, in contrast to the opening two races in Australia and Malaysia.
Even McLaren team principal Martin Whitmarsh has conceded to surprise at Rosberg's two-stop strategy given Mercedes' prior tyre issues, whereas Jenson Button and Lewis Hamilton were forced to make three stops en route to finishing second and third.
"I think we just hit the sweet spot with the tyres," said Brawn.
"We got the set-up right, we worked very hard at making sure we looked after the tyres, and the engineers and drivers did a great job of just keeping the car and tyres in that window where it works really well."
It is why Brawn is unable to predict whether Mercedes can be genuine title challengers this season, believing it is "far too early to say".
Much will centre on whether Mercedes have more "perfect" weekends as was the case in Shanghai, or more where they struggle for that aforementioned sweet spot as in Australia and Malaysia.
Brawn said: "It's so difficult to judge because of the sensitivity.
"Did everyone else get it wrong and we got it right, or did everyone get it right? Is it a fair measure of where we are? I don't know.
"But the fact we've been close in qualifying in the first three races gives me encouragement.
"It was just the perfect race for us, and I suspect it wasn't for others, so now we are going to turn as many races as we can into perfect races."
