Nico Rosberg insists he is far from worried about Mercedes recent struggles because he is adamant it is learning valuable lessons for next year.
Mercedes has failed to score a point since the Singapore Grand Prix - something only the three newest outfits have done as well in that spell.
And although that poor form is in stark contrast to the strong way Mercedes started the campaign, Rosberg believes the current situation is not leaving him uneasy about the state of the team.
"It is a concern? I don't know. I am not thinking about the past," he said when asked by AUTOSPORT for his feeling on the current points drought.
"What I am thinking about is we do the best we can at the moment to prepare ourselves for next year. For sure it is looking better. A lot better.
"The people are starting to have a good impact. All the new people, it has been a massive amount of new people....So we will definitely be better. I am not looking at the past races of anything like that."
Rosberg and team-mate Michael Schumacher have been switched back to Mercedes old exhaust configuration in Brazil in a bid to help the team's understanding of new tyres.
Although that decision highlights how much Mercedes has to learn about the preferred Coanda-effect layout, Rosberg is comfortable that lessons are being learned.
"We need to prepare for the new tyres because that takes out the complexity the temperature thing from the Coanda, and we can concentrate on the tyres," he said.
"It [the Coanda exhaust] remains complex and we are learning a lot. And we need to use these last races as there is no more testing and it is very important."
