Nico Rosberg admitted he was disappointed with only qualifying sixth for the Monaco Grand Prix having felt there was a real chance of fighting for pole.

The Mercedes driver was quickest through the second stage of qualifying but was unable to match that speed in the vital Q3 session.

Admitting that he had made a mistake on his quick lap, Rosberg will instead line up on the third row of the grid and he admitted to being frustrated at not being higher.

"My pace has been really good here throughout the weekend and in the first two qualifying sessions today, so it was a disappointing result to only qualify in sixth position," he said. "I was hopeful of competing for the front row after our performance in Q2 but the final session just didn't work out for us today. I had a lot of traffic to overcome and made a mistake on what should have been my fastest lap. Unfortunately the tyres were not at their best then for the final quick lap.

"It's difficult to make up positions in the race here as overtaking is almost impossible. However you never know what can happen and we will work hard to try and finish in a better position tomorrow."

Team-mate Michael Schumacher lines up behind Rosberg in seventh place on the grid and said he was confident of making up places in the race.

"Qualifying confirmed that the gaps between the teams are smaller here but not small enough to really get some profit out of it, which is what we would have wished obviously," he said. "We all had some concerns about qualifying because of the number of cars but I have to say that from my point of view, everybody did a great job. I had a clean situation most of the time, except for once unintentionally with Nico.

"I think we got out of the car what we could today and the positive news is that I am on the inside which is a good starting position and our starts have gone well recently. So we can at least hope to make up one or two positions for the race."
