Rosberg says Williams 'back to normal'

The British squad enjoyed a strong start to the season in Australia, with Rosberg finishing in third place and teammate Kazuki Nakajima in sixth.

However, Williams struggled in Sepang, where neither driver were able to get close to the top.

But after posting the third fastest time in this morning's practice and the sixth in the afternoon, Rosberg reckons Williams are back on form.

"I am happier with the car here compared to the last race in Malaysia and I think we are back to normal now, which is encouraging," said Rosberg. "The circuit surface suits our car better, which in turn made it much more enjoyable to drive.

"Over the two sessions we made some very big set-up changes and I think we've gone into the right direction. It's getting very close with a lot of people in the midfield, but I think we have a good chance to do well this weekend.

"It was also productive to be reliable today which meant plenty of track time."

Nakajima was also pleased with his day's work after posting the eighth quickest time.

He said. "Today we didn't have any problems, so we could use all of the practice time which was great. Initially in the morning session, I struggled a bit, but in the afternoon, we made a big set-up change which was very positive.

"We have a bit more work to do tomorrow, but it is a good start."
