Belgium preview quotes: Sauber

Sergio Perez: "After quite a long break when everybody was on holiday, it is nice to get back into the car again and to the race rhythm. I'm very much looking forward to the Belgian Grand Prix. Spa is a very special place. I think we can pick up again the momentum from before the race in Hungary, and do well there. It is one of my favourite circuits because I love Eau Rouge and the other fast corners. I won in Spa in Formula 3, and also last year in GP2. Personally the break was good for me to fully recover from the Monaco accident."

James Key, Technical Director: "We're looking forward to getting into the next part of the season and going to Spa, which requires a medium-to-low downforce level. To date it will be the lowest downforce level the teams have run, but a lot will depend on the weather conditions, because they are very unpredictable. As always in Spa, we have to monitor the weather closely over the weekend. The circuit itself is very popular with the drivers, and a great place to engineer a car. The track is primarily high speed with long straights and well known corners. This should suit our car reasonably well. The Pirelli tyres are the soft and the medium compounds. We know from Silverstone that the soft tyre works well with the high speed corners, but we have some work to do with the medium compound. The car will have updates to the front wing and a new rear wing which is Spa specific. After a difficult race in Hungary we're hopeful of a better performance in Belgium."
