Geoffrey Willis joined Red Bull last month. This is the first race he has attended with us.

Geoffrey Willis, Technical Director: After more than a year away from F1, it's good to see the cars in action and up close again. While there have been some regulation changes in that time, the racing challenge is very much the same, so it's interesting to see the differences in the Red Bull approach. Certainly the Red Bull Racing facilities and working environment at the track are impressive.

Having spent a month now with Red Bull Technology my first impressions are on the whole very positive, although there is plenty of work to do and as usual not much time to do it in! The level of competition in the sport is now so high that it is important that all parts of the team step up in performance level. Together with its excellent resources and new facilities at Milton Keynes, the team has a great deal of potential. It is an interesting and different new role for me and will, I am sure, provide more than enough challenges in the coming months.

David Coulthard: My car had a fuel leak and fire at the end of this morning's session, so the team had to find the leak and change the engine. The boys did a great job to get the car out again when they did, as there was a lot of much work to do – it was a good effort. Originally we were going to use the T car for the second session, but I wanted to stay with the race car, so we changed the engine instead. Once the car was ready, we got on with working through our normal Friday practice.

Mark Webber: I've been struggling all day in the car. We've got work to do this evening; we just need to get our heads down now and see where we can improve before the qualifying tomorrow.
