Lotus team principal Eric Boullier insists there is no sense of mounting frustration at his outfit, despite another weekend where it failed to deliver on its full potential.

The pace of Romain Grosjean and Kimi Raikkonen in the British Grand Prix suggested the car had the potential to fight the Red Bulls and Ferraris for victory - but both men were too far down the order to make the most of their chances.

Raikkonen's efforts in qualifying were compromised by a KERS problem that cost him lap time, while Grosjean had a spin in Q2 and then damaged his front wing on Paul di Resta's rear tyre on the opening lap.

Although both men recovered to finish fifth (Raikkonen) and sixth (Grosjean), their pace suggested that more could have been possible if Lotus had got everything right on each day.

But Boullier says that despite the fact the team could be left ruing another opportunity slipping through its fingers, he says there is no annoyance at what is happening.

"I have to say there is absolutely no frustration," Boullier told AUTOSPORT. "It's just the ninth race of the season. There are 11 races to go, it's going to come. Every race we are there, so it's going to come."

Boullier remains convinced that Lotus just needs to sort out qualifying to finally be able to deliver on its quick car in the races.

"We needed better qualifying from both cars actually," said Boullier, looking back at the British GP. "If we had put the tyres on earlier, maybe Kimi would have qualified better - in the top four - and starting in a higher qualifying position would have allowed us to win this race. And this is definitely the key.

"Again, our guys are fast in the race. We build up on a good strategy, but if we don't qualify better we won't be able to be stronger in the race."

He also thinks that qualifying further up the grid will minimise the chances of his drivers getting caught up in incidents - as has happened to Grosjean a number of times this season.

"If you start lower you cannot help getting involved in these issues," he said. "Each one was a different incident, with different reasons."
