Marcus Ericsson has heaped praise on Sauber for the way they bounced back this year, adding they will be even better in 2016.
The Hinwil-based squad endured a nightmare 2014 campaign as they failed to score a single point and finished 10th in the Constructors' Championship.
That led to several changes as they dropped both Adrian Sutil and Esteban Gutierrez and went for an all-new line-up of Ericsson and rookie Felipe Nasr.
There has certainly been a turnaround in their fortunes this campaign as they have already picked up 36 points and are regularly fighting for top 10 positions.
Ericsson, who joined Sauber from Caterham, admits things have gone a lot better than he expected.
"I didn't really know what to expect," he is quoted as saying by the official F1 website. "Sauber is a team with a great history but also Sauber had a very difficult year last year so when I joined it was absolutely not clear what it would be and were we would start from.
"To be honest it outperformed my expectations – we have been points candidates in almost every race."
Sauber were one of the first teams to confirm their line-up for the 2016 season with the team opting to stick with Ericsson and Nasr and the Swede believes continuity will be key to further growth.
"I think it will be better as it will give stability to the team," he said. "We know now the in's and out's; we know the working procedure; and we know the mentality.
"We are both very involved in next year's car – speaking with the engineers about what we want from the car."
