Coulthard disappointed despite top ten

David Coulthard said he was disappointed despite putting on his strongest qualifying performance of the season ahead of the Spanish Grand Prix

The Red Bull Racing driver made it to the final shootout for the first time this season, showing the progress made by his team since the last race.

The Scot, however, admitted he was hoping for more.

"I'm disappointed to have ended up in ninth position today, as I think the car's quicker than that," said Coulthard. "Unfortunately I suffered a lot of understeer on the new tyres, which made it very difficult."

Teammate Mark Webber endured a tough session, the Australian failing to get past the first part of qualifying. He will start the race from 19th position.

"Saturday was a tough day for us," admitted Webber. "We didn't have a smooth practice session and the first part of qualifying didn't go to plan either. We had drive shaft problem this morning and a hydraulic problem in qualifying.

"Of course, we've learnt some things, which isn't ideal at race weekends, but sometimes you have to go through that to move forward. The mechanics have been phenomenal; the work they're doing before races and the practices is very good.

"David had a good run today, which shows the car has potential, we just need to work at pulling the whole thing together now."
