Paul di Resta says he hopes Force India will be able to build on its Monaco result in Canada this weekend to close the gap to the teams ahead in the title race.

Di Resta and team-mate Nico Hulkenberg secured a double points finish in Monte Carlo in what was Force India's best result of the season so far, although the Silverstone-based squad heads into the Montreal race sitting eighth in the championship.

Rivals Williams and Sauber have benefitted from somewhat surprising results earlier in the season - with Sergio Perez taking second in Malaysia and Pastor Maldonado winning in Spain - but di Resta insisted that Force India was making good progress as it seeks to close the gap.

"I think me and Nico have a good relationship, we're obviously pushing each other along but also trying to develop the car because we feel that we're a little bit behind the likes of Sauber and Williams at the moment," he said. "To overcome that we need to be doing a good job in the race. Over the weekend you've got to maximise what you have, and that's what we're going to try to achieve again this weekend.

"We need to understand the car a bit more in terms of what we're bringing in terms of upgrades. That's what we're trying to achieve. But I have every confidence the team will achieve that because last year our development rate went very high from mid-season, so we're certainly hoping we can do that this year. I don't believe we're getting the maximum out of the car yet but we'll try to achieve that this weekend again. It's a different philosophy, obviously, being a bit lower downforce here. So hopefully that will suit us slightly better.

"It wasn't a secret that we struggled at the beginning of the year, to what we initially first thought. Since then we've rapidly moved on. I think we bought a good upgrade to Barcelona. We obviously developed that forward over that weekend. Monaco was difficult to understand how much so I think here will probably be a truer reflection on what we can expect for the up and coming races."
