Rosberg unsure what to expect

Chinese Grand Prix winner Nico Rosberg say he and his Mercedes team are unsure of their competitiveness in Bahrain.

Rosberg’s record in Bahrain is excellent, with a podium finish in F3, two victories in GP2 and fastest lap and a points finish on his grand prix debut. “This is a track I really enjoy, I’ve had some very good memories here but again it’s just difficult to know where we’re going to be exactly,” he said, speaking in the FIA Thursday press conference. “In Shanghai of course we did very well but previously we had a few issues in the races, so it’s possible it’s going to be a bit more difficult here.”

While there has been a suggestion the Mercedes victory in Shanghai was aided by unusually cool track temperatures, Rosberg argued that his team had been making genuine improvements in the first month of the 2012 F1 season. “The engineers and everybody have really been making some good progress on the car, setup-wise, so we’re learning very quickly. It wasn’t a coincidence that we were fast in Shanghai. No, we did a good job and got the best out of it – but the situation could be different here with the temperatures and that might prove a little bit more of a challenge.”

While Rosberg was happy to take some of the credit for his win in China, he rejected the notion that he, rather than the car, was responsible for the victory. “Definitely not,” he said. “It was just that everything came together: I was on top of my game for the weekend in qualifying and the race, but also the set-up – the car was working very well. It was enough to win by some margin. All in all, it was a really strong weekend.”
