Monaco Thursday quotes: Sauber

Sergio Perez - 12th: "It was a good day for me. We had a huge programme and have done a lot of work. In the morning session it was a bit difficult with the tyres, because we went out early and then their performance dropped off. In the afternoon I tried the super soft tyres for the first time, and also did a long run on them. I really hope we will be able to do a good qualifying. With the Formula 1 car it is obviously even more difficult to overtake here in Monaco than it was with a GP2 car."

Kamui Kobayashi - 16th: "For me it was a little bit tricky today. My car was bouncing too much, therefore the balance wasn't right either and I didn't have enough grip. We have to find something to get rid of the bouncing. It was so bad that I feel I cannot really make a judgement on the tyre comparison. Regarding the rear wing, I would say it doesn't make much difference in Monaco whether you have DRS or not, except it keeps you busy. Either way overtaking is extremely difficult here."

James Key, Technical Director: "We have had a normal first day of practice here in Monaco. As is usual at the beginning of the Grand Prix weekend, the grip level was very low. In the first session we went out early with both cars to give the drivers a good chance to adapt, but this also meant the tyres were finished quite early. The suspension parts we brought to the car worked as expected. In the afternoon we compared the tyre compounds - the soft and the super soft. We did long runs with both and they are working well. We now have to analyse our data and need to work on our performance on fresh tyres for qualifying, because that is the part which is not quite a hundred per cent."
