Sebastian Vettel says Red Bull have lost self-belief after failing to replicate last season's dominance so far in 2012. Red Bull won 12 out of 19 races in 2011 and took 18 pole positions to wrap up their second world titles in as many seasons.

But it took until the fourth race in Bahrain last weekend for Red Bull to earn a win, courtesy of Vettel. "We're not as confident as we used to be," he said. "So small things can make a difference in qualifying and have a big impact on the race. I'm not entirely happy with where we are, but there's great potential in the car."
