Horner says win redefined goals

Sebastian Vettel led team-mate Mark Webber to a one-two in Shanghai, as Red Bull confirmed its position as one of the favourites to fight for the titles this year.

The team from Milton Keynes has been on the podium in all races since winning, and Hornet admits the goal now is to catch championship leader Brawn.

"The team is on a high after the result in China, which was backed up by Sebastian's podium in Bahrain and Mark's in Barcelona," Hornet told the official Formula 1 website.

"China was a milestone. We have the first pole position out of the way and have the first win out of the way and that automatically changes our focus.

"Our focus now is very clearly to close the gap to the Brawns - and Barcelona has shown that we have done that - and we still have a lot more development potential open to us. The car is performing very well, the team is performing exceptionally well, and we are going in the right direction."

Horner insisted the team is working hard to introduce a double-decker diffuser, a task that it's harder for Red Bull because of the design of the car's rear suspension.

Despite that, Horner is hopeful it will be run in the next race in Monaco.

"It is a big challenge for us to incorporate a new floor given the characteristics of the RB5," he added.

"Probably it is more difficult than at other teams, but be assured that the guys back home in Milton Keynes are working very hard on a solution and hopefully Monaco will be its first race."
