Sauber team principal Monisha Kaltenborn is "absolutely confident" that the team will can bounce back from its poor season so far.

After 11 races Sauber is yet to score a point and sits in 10th place in the constructors' championship behind Marussia. While 2014 has been a tough year for the team so far, Kaltenborn believes there are signs of recovery and feels the current standings don't reflect the opportunities that Sauber has had at various races this season.

"I am absolutely confident that we will move back up again," Kaltenborn told the official F1 website. "It will take a bit of time. We are moving in the right direction - and, of course, I hope that things change in this season - so I take it event by event. We had our chances in the last few events but haven't made use of them. We have to make sure in the race that we don't make mistakes when these opportunities come up."

And Kaltenborn says the progress the team has been making with the chassis bodes well for next season's car.

"The emergency plan is pretty simple: scoring points, a point. Yes, we've had a very rough start, but looking at our side - the chassis side - we have made steps and introduced improvements. It's just that when the gap is so big you don't immediately see that improvement from the outside, nor in the performance or in points. We have to keep to our path.

"The advantage compared to last year is that there is not such a massive change for 2015. What you do now can be used next year. I also can say that from the powertrain side our engine supplier has been doing a lot and I know that they are absolutely flat out in wanting to make improvements. So we will get there together."
