Felipe Massa believes that Williams must target overhauling Ferrari - and perhaps Red Bull - in the Constructors' championship.
Massa, who claimed pole position in Austria, was eliminated on the opening lap of the British Grand Prix but team-mate Valtteri Bottas finished in second place to put Williams within touching distance of Ferrari in the title battle.
"I think we always need to think about getting better," he said.
"We improved step-by-step - we didn’t bring pieces that make the car completely different, we’re doing a good job on the development.
"In the last three races we were stronger than Red Bull and Ferrari. So if we are better than them in terms of pace, why can't we fight with them?
"At the moment we are a few points behind Ferrari and a bit ahead of Force India and McLaren. We need to fight to stay ahead of them but also Ferrari – Red Bull is maybe a bit far but you never know."
Massa believes that Williams's pace at the last two events justifies his high target.
"It [his British Grand Prix retirement] took me a lot of points as the car was amazing, so competitive, but I’m still convinced and motivated that everything will come normal," he said.
"Whether we can fight with the big teams like Ferrari and Red Bull... I believe this is possible. It’s the way I’m working and the way I believe."
