Wednesday 9 July at 12:15 : Williams will revert more effort into improving its current formula one car.

Patrick Head, the British team's co-owner and engineering veteran, revealed that much of the focus at Grove recently switched to preparing for next year's sweeping technical rule changes.

"We are retro-putting some attention back to 2008 because we need to do better than we are doing," he is quoted as saying by the BBC.

Williams currently lies sixth in the constructors' championship, just one and two points respectively in front of Renault and Honda.

Head also admits to speaking with Nico Rosberg, who has not added to his personal points tally in the past four races.

"It's obviously not ideal but what do you do? You sort it out and that's what we'll do," he said.

Head said he, team boss Sir Frank Williams, technical director Sam Michael and Rosberg already had "a very straightforward talk" after Montreal, when he crashed into Lewis Hamilton in the pitlane.

"There were no harsh words, no raised voices," he said. "Obviously we work as a team but in effect Nico didn't get the results that he could have got and he's aware of that."
