Sergio Perez believes Force India can overhaul Williams for fourth in the 2016 Formula 1 constructors' standings, but says it cannot afford to repeat the double DNF it suffered in Austria if it is to achieve this lofty objective.

After an indifferent start to the season, Force India has thrived since the introduction of the revised VJM09 at the Spanish Grand Prix, with Perez notching up podiums in Monaco and Azerbaijan, while Nico Hulkenberg was a front row starter last time out in Austria.

With Force India intermittently proving to be the most competitive team behind the 'big three' of Mercedes, Ferrari and Red Bull since Barcelona, Perez was disappointed that brake problems - which pitched him out of eighth place on the final lap - would see Force India come away empty-handed in Austria.

Nevertheless, ahead of the British Grand Prix, Perez remains confident Force India has the pace and time to bridge the current 33 point margin to Williams for fourth in the constructors' standings.
