Coulthard frustrated despite point

The Red Bull Racing driver had put on his best qualifying performance of the season on Saturday, starting the race from fifth place.

However, the race proved disappointing for Coulthard, who lost three places and had to be content with a single point from eighth position.

"A frustrating race," said Coulthard. "To start fifth and finish eighth is pretty disappointing, but at least we take a point from China and move closer to Williams in the battle for fourth in the championship.

"It was a bit of a lottery with the tyres today and unfortunately at the point I changed to dry tyres it started to rain lightly costing me around 30 seconds in two laps."

Teammate Mark Webber also endured a disappointing day after failing to score any points. The Australian paid the price for switching to wet weather tyres too soon and went on to finish in tenth.

"I had massive understeer on my wet tyres in the first stint, which made it very difficult to get through Turn one and twelve - important corners for laptime," said Webber.

"I made the call to go to dry tyres, which was about the right time for my pitstop. It was a tough call to know if wet or dry tyres were best.

"Once on the dry tyres, the rain started again and I saw a car off the track on the last corner and also had a moment myself. I made the call to put wets back on, which wasn't good, as the rain didn't last for long, so I had to go back onto dry tyres again.

"Unfortunately, we didn't quite get it right today. David's point has closed us up to Williams a little bit, so let's see what we can do in Brazil."
