Force India team principal Vijay Mallya believes his outfit can catch Williams in the Constructors' Championship.
Williams have enjoyed a great season so far, picking up three podiums to find themselves fourth in the standings behind Mercedes, Red Bull and Ferrari.
Their Silverstone counterparts are one spot below and 37 points behind, but Mallya is confident his Force India squad can make up the ground in the remaining eight races if they all pull in the same direction.
"Like us they have the best power unit, so that definitely gives them an advantage over where they were last year. And don't forget, in pre-season testing Williams showed their pace," he told the official Formula 1 website. "It was very clear that they would be very competitive. In fact I was a bit surprised that they didn't do in the first couple of races what they've done in the last few races. So we definitely will not make the mistake of underestimating them.
"Can we catch Williams? Yes, we can. We have to work hard at it as well, but as I just said, there's still a long way to go. They have done a great job and one should complement them for this - probably in the same way that we are doing well - unexpectedly - as a midfield, small team. The opportunity is there."
