Nico Rosberg says it is vital he regains the upper hand in his battle with Lewis Hamilton at this weekend's Spanish Grand Prix, after finishing second to his Mercedes team-mate at the last three races.
Rosberg still leads the drivers' championship by four points, but Hamilton has the upper hand on track after three consecutive victories. After qualifying fourth at the last race in China and fighting his way back to second, Rosberg is looking for a clean race weekend to get the better of Hamilton in Spain.
"Every weekend is crucial, but the momentum is on his side at the moment and we need to try to turn it around definitely," he said. "I'm here to win in Barcelona and try to extend the lead in the championship."
Rosberg said he does not need to change anything specific, but just needs a weekend without any issues.
"Definitely I'm comfortable to keep doing what I'm doing. What I need is a normal weekend, because I haven't had one of those lately. I just need a normal weekend and then I'll be able to turn it around.
"Just a straightforward weekend without complications. In China there was many of them for the whole weekend, so it really was a damage limitation weekend for me and with second place it really was the perfect damage limitation. I just look forward to a weekend without too many complications, then I'm sure I will be a lot stronger."
Rosberg said he expected Mercedes' rivals to be closer in Spain due to the nature of the track and the development possible in the three-week gap since the last race in China.
"Yes, I expect people to be a bit closer here at this track. Again because there has been time to develop and also because engine power is that little bit less important than it was in China, for example. I hope we have pushed on with the development a bit and that we are able to keep our gap. But for sure people like Red Bull, which is still the benchmark team in the sport, we are expecting them to push on and try to close the gap."
