Sebastian Vettel, Red Bull, Sakhir, 2009Sebastian Vettel says he has put last weekend's Chinese Grand Prix triumph behind him and is focusing on his program at Sakhir.

The German ended Friday's free practice in fourth position, one place ahead of his Red Bull teammate Mark Webber, adding that it is business as usual for the two-time grand prix winner.

"Obviously it's back to normal now," he said. "Last weekend was fantastic, but we have to carry on as there's a lot of work to do! So our minds are now set to focus on Bahrain.

"It was a normal Friday, we were more or less able to do our full program and had no issues with the car. Performance-wise, it's difficult to comment, but the car feels alright. We were struggling to find a good balance this morning, but it was better this afternoon.

Webber agreed that he found it tricky to establish a balance with his RB5 on his way to fifth fastest time: "We have very dry conditions and, as usual, Bahrain throws up its challenge with car balance.

"We had a productive Friday, running on both tires and the car ran faultlessly," he added, "In terms of pace it's always hard to say who's where on Friday - but hopefully we're in good shape again to get some good results on Sunday."
