Barrichello not expecting big leap soon

The team from Grove is currently seventh in the standings, having score only six points in the first four races of the year.

Barrichello says Williams has understood how to solve some of its issues, but reckon it is unlikely the team will be able to take a very quick step forward.

He is confident, however, that the development push will help Williams be more competitive as the season progresses.

"We know how to address some of the problems," Barrichello said. "I don't think we'll find a second all of a sudden, but the thing that I know for sure is that this car is like this and they will be develop the car until the very last moment.

He added: "I think we will have to work make the top six in qualifying. The race is a different matter. You need reliability, different things. To get into the top six all the time we need to find half a second."

Barrichello says he is pleased to see the team is listening to his suggestions, and agrees that both parties are unhappy with the results so far.

"We have a good harmony between driver and team and the great thing is that I can quite clearly say that I'm not happy with the result, because the team is not happy either," he added. "We just need to keep on moving.

"Unfortunately, even with all my experience, new things happen and you keep learning, and that's how life goes.

"The team is prepared to listen to me, which is great. The team is really relaying on my calls and I'm feeling great on that."
