Nico Rosberg insists Mercedes should not be overly concerned by reliability issues due to the dominance of its car.

Singapore saw Rosberg retire early in the race and team-mate Hamilton took the championship lead with victory. With double points available for the final race and Daniel Ricciardo 60 points behind Hamilton, Rosberg admits reliability is a weakness for the team but says he has an "inner trust" that Mercedes will close out both championships.

"I'm not concerned," Rosberg said. "Even though it is a little bit of a weakness for us but in the big picture we have done an awesome job this year. We mustn't now see this as a big problem for us as a team. It is a problem that we have but the big picture is the absolutely spectacular job that the team has done full stop. I'm not worried about reliability, I have this inner trust that the team is going to get the job done and so it's not something that I really think about at all."

And Rosberg also said the disappointment of losing the championship lead in Singapore is fully behind him.

"It was just a tough moment but time is the best cure for such things and there's been two weeks which is plenty of time in the racing world. For me it's completely forgotten. Now I'm here I'm just as optimistic and excited as I was before Singapore, and I'm just looking forward to it because I'm in Suzuka; I've never come to Suzuka - which is one of the best tracks of the year - with the best, dominant car.

"I've never had that before, so I'm coming here, I know I'll have a chance for pole on Saturday and a chance to win the race on Sunday. That's just a great feeling and that's it, that's just my state of mind at the moment."
