Mercedes driver Nico Rosberg is confident of a good performance in tomorrow's Singapore Grand Prix after impressing in qualifying.

Rosberg finished the qualifying just 0.091s behind Sebastian Vettel and believes that he should have got the pole position.

"It was very, very close, and in the end a pity because one more 10th [of a second] would have been possible somehow," Rosberg told reporters.

"Second place is still a great result and gives me a good position to start the race tomorrow. Our race pace was strong on Friday so I'm feeling confident for tomorrow evening.

"I doubt if we have enough performance to beat Sebastian but I'll do my best to have a good start and then we'll see how it goes from there."

Rosberg's teammate Lewis Hamilton qualified fifth for tomorrow's race and is targeting a podium finish.
