Kubica laments lost track time

The afternoon session had to be red flagged for a total of 28 minutes after a drain cover worked loose at turn 10.

The delay meant Kubica and his BMW-Sauber team were unable to complete their scheduled programme.

"This morning the track was really slippery and many drivers went off, so the conditions were very difficult," said the Pole, 10th quickest. "In the afternoon the conditions were better, we mainly concentrated on the long runs to compare the tyres and we have done some good work.

"Unfortunately the session was stopped for quite a while, so we had to drop some set-up work, but we have some time to do that tomorrow. I would have liked to do one more run, but it was the same for everyone."

Teammate Nick Heidfeld, 13th fastest today, said there was still work needed in order to be competitive over long runs.

"I enjoy driving here and I like the track, although in the morning in particular it was very slippery," said Heidfeld.

"Despite losing almost half an hour of track time, we completed all the important jobs and compared the two tyre specifications. The set-up is not ideal yet and, in my view, my long runs at the end were not perfect either."
