Red Bull's boss Christian Horner has conceded that his team's crushing defeat by McLaren and Ferrari in the German Grand Prix shows they need to work harder in Hungary this weekend.
Horner admitted there was nothing his drivers Australian Mark Webber or defending champion and current leader Sebastian Vettel could do to stop Lewis Hamilton and Fernando Alonso finishing first and second in Germany.
But he says Red Bull has still had pole position at every Grand Prix this year, won six out of 10 and been on the podium in every race.
There have been four different winners in the last four Grands Prix after Vettel began with five wins in the opening six races this season.
