Kubica delighted to hold on to fourth

Kubica, who had qualified in fifth place with his BMW Sauber, benefited from Massa stalling before the start of the race to move into fourth position.

The Pole held on to that place despite the Brazilian putting big pressure on him during the final part of the race.

"I am very happy," admitted Kubica, who had also finished in fourth position in France a week ago.

"I found myself in front of Felipe Massa, but this race was not as easy as in Magny-Cours as I had to keep him behind me for the last 13 laps. Being behind here is tough as Felipe lost a lot of downforce, although he was quicker when he was alone on the track.

"He had a harder job than me as I just had to control the situation, not push too much, not make any mistakes and I was pretty sure I would hold him. In the middle of the race it was quite easy for me, but as soon as I heard over the radio that Felipe was closing the gap I tried to push.

"I did everything to get the maximum from the car and from me. We are happy to finish fourth, the car felt good and now we have to maximize our potential. Fourth second time in a row and ten points from this isn't bad."

Teammate Nick Heidfeld finished in sixth position after having started from ninth. The German admitted he was happy with his performance in the race but was left lamenting his poor qualifying.

"I am very happy with the race, but not with the race weekend overall," he said. "I started from ninth and finished sixth, three seconds behind Robert.

"The start was special. I didn't really accelerate better than Giancarlo Fisichella, but overtook him in the first corner on the outside, which I enjoyed, although at the exit of turn one we banged wheels. Later he caught me on the Hangar Straight.

"I was aware that Felipe Massa would have his second pit stop later than mine, but the advantage of a low fuel load is quite big here, so I could not stay in front of him. All in all I think a better grid position would have improved my chances significantly.

"The two leading teams are not running away from us and we had Renault under control again. We couldn't have asked for more today."
