Glock not too worried about points

The iSport driver made a dominant start to the season, but he has failed to finish in the last four races, and he is now just two points ahead of ART's Lucas di Grassi.

However, Glock is still confident that he can hold on to the championship lead as he has still had good pace.

"We'll be up there again, we know we have the pace," said the German. "But also you need the luck on your side.

"Unfortunately we didn't have it on the last two weekend, I just hope that we get it back."

Glock's poor run started when he collided with teammate Andreas Zuber at the start of the first race at Magny-Cours, and at Silverstone he had a battery problem in the first race and collided with Adrian Zaugg in the sprint race.

While he took some comfort from the fact that Zuber took a win for iSport last weekend, he did admit that the last two race weekends had been frustrating.

"It's quite tough," he said. "It's really frustrating  when you know you have the car to be up there and can't use it.

"You just have to take a look at the championship and see how quickly the lead can go away."
