Force India deputy team principal Bob Fernley says his squad has been "thrilled" with the performance of Nico Hulkenberg and Paul di Resta this year.
Both drivers have impressed throughout the campaign and at Spa last weekend both raced strongly, with Hulkenberg finishing fourth and di Resta grabbing 10th despite being slowed by a KERS failure. Fernley says the team cannot fault either of its men in the cockpit.
"I think Nico has done a super job, we never had any doubts about him, and with Paul they are just so equal," Fernley said. "There is nothing between them and it is a thrill to have two wonderful drivers pushing the limits all the time."
Fernley hopes that the performance at Spa bodes well for the rest of the campaign, as it suggests the outfit may have made progress in addressing problems it has had carrying its speed throughout the races.
"We probably need a little bit more to get the last qualifying runs in as we have been making the odd mistake here and there," he said. "But the biggest problem we have had is holding on to it [qualifying position] in the race. At Spa we got the balance about right and hopefully we can continue that into Monza and Singapore. We just have to capitalize now on the momentum."
Hulkenberg and di Resta's points from the Belgian Grand Prix helped lift Force India past Williams and into seventh place in the constructors' championship.
