Brazil Saturday quotes: Red Bull

"I've scored points from the back of the grid before and it's not over until the chequered flag, but clearly this makes it a lot more difficult to get a good result."

Robert Doornbos - 15th: "We really wanted to attack in the last qualifying session of the year and I think we did that. The sessions are a lot of fun - you can really drive on the limit and get the maximum out of the car. I think I got the maximum out of the car today. We've gone through tomorrow's race in our minds set-up wise, and we're going to be pushing hard."

Christian Horner: "Obviously,  it  was  a  disappointing  qualifying  session  for  David  who hasn't been happy with the balance of his car all day. Robert did a good job. We decided that he'd only do one run in the second qualifying session, due to knowing what our limitations are and  the  ten-place  grid  penalty we collected for Robert's engine change. Hopefully, we'll be stronger in the tomorrow's race. "
