Mark Webber says he is relaxed about Red Bull's reliability, despite the issues that have hampered the team in recent races.
The Australian suffered hydraulic problems during the European Grand Prix weekend that meant he started from the back of grid, while team-mate Sebastian Vettel retired from the lead of the race after being hit by an alternator problem.
Webber insists however that he has no worries the problems will continue.
"I would've been concerned five or six years ago, but we weren't a world-class team then," said Webber ahead of the British Grand Prix.
"Now we are. These guys get their sh*t together pretty fast. I'm pretty relaxed. You've got to stay in the hunt to win. It is tight between lots of different people."
Although Vettel was putting on a dominant performance until his retirement, Webber does not believe Red Bull will be miles ahead of its rivals this weekend and in fact reckons McLaren is favourite for victory.
He does concede though that Red Bull took a step forward at Valencia.
"For sure, we could make the car slower in Valencia! It was a step in the right direction. We're not kidding ourselves we're going to drive away from the field. It was a good weekend for us," he said.
"McLaren are probably the favourites around here. But the form card is very hard to predict."
