Nico Rosberg has said the Austrian Grand Prix turned out as he expected and that Mercedes were confident they could beat the Williams' of Felipe Massa and Valtteri Bottas.

Rosberg started from third behind both of those cars, and while he initially got ahead of Bottas off the start, he was soon passed. However he jumped both of them in the first round of pit stops and then never really looked back - even if he did have team-mate Lewis Hamilton right behind him at the chequered flag.

"To be honest yes, it did pretty much [turn out] exactly like we were trying to make it work," Rosberg reflected. "OK I thought I would get Valtteri at the start and I did, but they are quick on the straights and he went straight by me again, which was not good. But I knew pre-race even if I was third after the start my chances were still very good because we just had a little bit more pace and less tyre degradation than the Williams - or we expected to have less at least.

"So we progressed during the stops and it worked out really well. I am happy with the result. Also, it is great to extend the championship lead. That was really my goal coming into Austria."

"It wasn't the easiest of races, however, and we had to try and manage some things which were a bit on the limit," he added.

"Still it is fantastic to win here and get a 1-2. It is great to come back here [to Austria]. It has been an awesome weekend."

Meanwhile, Rosberg added that he didn't really feel threatened late on when Hamilton closed up in the final few laps in the sister Merc.

"I generally felt comfortable. I thought I could keep Lewis back. It was just the last lap my tyres dropped away a little bit but as soon as I got passed the first couple of corners I knew it would be fine. It wasn't as close as some of the other races more recently," he added.

Rosberg now increases his lead over Hamilton in the Drivers' Championship to 29 points, but he isn't getting carried away.

"It is a nice gap. But it is still early in the season. I am still concentrating on each weekend and trying to make the most of them.

"We are taking it step-by-step and every weekend I aim to extend my championship lead, which I managed to do this weekend," he concluded.
