Paul di Resta has urged Force India to up their game after taking their eyes off the ball in recent weeks.
Force India had an impressive start to this year's Championship, scoring points in seven of the first eight grands prix to move up to fifth in the Drivers' Championship.
In recent weeks, though, their grip on that position has slipped as the team failed to score in Germany and Hungary.
This has allowed McLaren to close the gap with the Woking team now just two points off the pace.
And di Resta, who finished fourth in Bahrain, says the team has only themselves to blame.
"I trust the team will have a lot of ideas as we go into the summer break," the Scot told Autosport.
"I think they have done a great job up until now, but we've let things slip slightly as a team in the last couple of grands prix.
"They're good guys and I believe they can work their way and come up with a solution."
The Scot, who is intent on moving up the grid next season, is hoping for better at the Belgian GP as he believes the Spa circuit will suit his VJM06.
"The track [the Hungaroring] didn't suit us; hopefully when we get to Spa with our lower downforce it will suit us," he added.
"We need to be doing a better job towards the end of the year and we'll try and do that as a unit."
