Wurz happy despite no podium finish

The Williams driver made the treacherous conditions work to his advantage, moving into the point-scoring positions after having started from 12th on the grid.

Wurz kept his cool during the whole race and came close to passing Red Bull's Mark Webber on the final corner.

In the end he had to settle for fourth, but the Austrian veteran was still delighted.

"I could almost taste the champagne today," said Wurz. "I am very happy with fourth position and a lot of points. It was a very tough race, I had to use all my brain power and push at the right times.

"The hardest thing out there today was keeping my head calm because in such a situation it is so easy to get carried away.

"I had to concentrate and bring the car home. My car was good today. In the last few laps I put a lot of pressure on Mark Webber because I saw he was sliding a bit and I was hoping he would make a mistake.

"He did make a small one, right at the end, but it was not enough to launch an attack and, of course, my main target was to bring points home for the team. One could say finishing just 0.2 seconds behind a podium position is frustrating, but I'm happy with fourth."

Teammate Nico Rosberg's race lasted just three laps, the German losing control of his car at the first corner when the rain hit the track for the first time.

"The start lap was very difficult on the hard tyres," said Rosberg. "It wasn't easy to warm them up and I seemed to struggle more than the cars around me. We knew the rain was coming, and we came into the pits at the right time, but we didn't expect so much water and we fitted my car with inters rather than full wets.

"I went back out on track and after some time there were yellows going into the first corner. I slowed down a lot but I aquaplaned and slid into the gravel.

"In such a situation, the tyres just come up and sit on top of the water and you have no contact with the ground. The engine then stopped and that was it. It was very disappointing. I'm now looking ahead to the next race."
