Monaco Sunday quotes: McLaren

Jenson Button - DNF: "That was extremely disappointing. I knew after the formation lap that there was a cooling cover left on the left-hand sidepod, where the radiator is. We thought everything was going to be okay, and it would probably have been fine if we hadn't had a Safety Car. My car quickly began to overheat and I started losing engine power, so I turned the engine off pretty sharply because the last thing I wanted was to leave engine oil on the racing line. Today was just one of those days. It was human error, a mistake, and that's all there is to it. I'm still only eight points behind the lead of the drivers' championship and we head to Turkey feeling confident that we'll be more competitive there."

Martin Whitmarsh, team principal: "Lewis scored a useful 10 points as a consequence of his solid run to fifth place - which, since overtaking is notoriously difficult here at Monaco and since there was no attrition in front of him, was as good a result as he could realistically have hoped for from his fifth position on the grid. He drove faultlessly, in fact, looking after his brakes and tyres throughout.

"Jenson's afternoon was very disappointing one for him, through no fault of his own. Human error caused a cooling cover to be left off the left-hand radiator on the lap to the grid - and, despite our best efforts to recover the situation, the components underneath the car got too hot, and Jenson was forced to switch the engine off when a small fire developed."
