An upbeat Nico Rosberg believes Williams can now set it sights on closing down on Ferrari, judging by the encouraging progress made with its car this season.
The German is delighted with the rate of development his team has delivered so far this season and sees no reason why the outfit cannot now close down on Ferrari in the Constructors' Championship.
"It is nice to see that in the past years we have been dropping back, and this year we are outperforming teams like Ferrari in development," said Rosberg. "So that is really nice to see, especially with the budget that we have it is fantastic. It really represents a lot of efficiency and good management and everything.
"We are now fifth in the Constructors' Championship, beating McLaren, and it should put us in a good position to attack Ferrari who are still in front of us if we have some good races."
Rosberg says he has been impressed by the way that Williams has operated this year -- with the team taking on board the lessons of a troubled 2008 campaign to really make big progress.
"It is very satisfying yes," he said. "In the last couple of races we have been developing strongest out of everybody -- maybe apart from Red Bull, who are making big progress -- which is very nice to see. It makes me happy also to know that.
"There was a little bit of a worry that as the season goes on, we didn't really make the most of the beginning of the season -- we weren't far off but we could done better, and perhaps missed our opportunity to do something special. But it looks like we will have many more chances."
And with Rosberg currently considering his future options, he admits that Williams's progress this season is making his decision about what to do in 2010 so much more difficult to make.
"It is massively hard at the moment. The team is doing so well, and I feel comfortable in the team also obviously. It is a nice team to be part of, and they deserve it also. It is nice to get some results. It is good."
