Korea Friday quotes: Sauber

Sergio Perez - 16th: "It is a shame but there wasn't much more we could have done today. There was just too much rain, and I didn't do a single lap on dry tyres. For me it wasn't an ideal Friday at all, as I don't know the circuit. Now tomorrow I won't have much time to get the balance of the car right."

Kamui Kobayashi - 17th: "There was no grip at all. The track itself has a very low grip level, and on top of that our car doesn't make very good use of the intermediate tyres. In general I don't mind driving in the rain, and with the full wet tyres it was no problem, but later with the intermediate tyres I was struggling a lot. It seems to take a long time for this circuit to dry out. In any case, I hope we will have dry conditions tomorrow."

Giampaolo Dall'Ara, Head of Track Engineering: "As the forecast predicted, it was a rainy day. However, for the remainder of the weekend we expect dry conditions, so we just did some running to do some checks on the car. We know we will have a very full programme tomorrow to do all the work necessary to find a good dry set-up."
