Mark Webber was frustrated after the Italian Grand Prix despite retaking the world championship lead - as he felt his Red Bull team should have made up more ground on a day when Lewis Hamilton retired.
Having made a poor start and then been elbowed back to ninth on the first lap, Webber could only recover to sixth place. With Hamilton damaging his McLaren on the first lap, the Australian now has a five-point lead in the standings, but felt it should have been more.
"We underperformed as a team today," Webber told television reporters.
"We could have capitalised and got more points, but we sniffed around just getting a few. It's a bit disappointing, but at least we got some [points]."
He was extremely unhappy to have been caught up behind Nico Hulkenberg in the closing stages. Although he eventually overtook the Williams, Webber had been annoyed that Hulkenberg had cut across chicanes on several occasions without being penalised.
"Obviously lost a lot of time behind Hulkenberg," said Webber. "He spent every second lap going through the chicanes [run-off]. The stewards did a hard job on him... they left him alone, so that was interesting. That was my race."
The Australian said that going back into the championship lead was not really any consolation.
"You've still got to make the most of opportunities, so it wasn't the best day," he said.
