Nico Hulkenberg had no complaints with his tenth place in qualifying, revealing that Sauber are battling with the balance of their car.
The German driver has been in fine form in the run-in to the season finale and on Saturday secured his sixth successive visit to Q3.
However, contending an ill-handling Sauber C32 in the rain, Hulkenberg could only manage a 1:29.582 which put him tenth on the grid.
"Reaching Q3 today was a success," said the 26-year-old.
"It's been wet the whole weekend, and we've not been as competitive as I would have liked as we had problems with the balance of the car.
"It was difficult to nail every corner as the track was extremely slippery.
"At the beginning of the season we were better on wet tyres and not so competitive on slicks, but now it seems to be the opposite.
"I think it will be an exciting race tomorrow and let's wait and see what the weather will be like."
