Monaco Sunday quotes: BMW

Robert Kubica - DNF: "We had difficulties over the entire weekend. I had a problem at the start and fell to the back of the grid. Then I had a puncture on my rear right tyre. After the necessary pit stop I was lapping well with a very heavy car - taking the car's potential into account. In the end I had to retire as I had brake problems."

Mario Theissen (BMW Motorsport Director): "A better result was not possible for us here this weekend. At no point was our car competitive. No points are the result. We have to improve our speed of development significantly in order to match our own expectations. Robert had a damaged tyre on lap two and later on suffered from brake problems, which caused him to retire. Nick was the first driver to change to the softer tyre compound after a long first stint. Nobody else was on Option tyres for such a long period, and they degraded dramatically before recovering a little towards the end of the race."

Willy Rampf (Head of Engineering): "After the free practice and qualifying sessions it was clear that today's race would be difficult. Nick's race ran without any special incidents. In the closing laps he was able to defend his position against Lewis (Hamilton) with worn out soft tyres. Robert had a flat tyre early in the race. Surprisingly, he was then able to do good lap times with a very heavy car. We had to bring his car back to the pits early due to a brake problem. Overall, this was a disappointing weekend. It is now our goal to be competitive again in Istanbul. A lot of work lies ahead of us."
