Sauber team principal Monisha Kaltenborn says she feels the Swiss team is taking steps forwards as it seeks to return to the kind of form displayed last year.

Having been one of the top midfield outfits in 2012, Sauber has struggled to replicate the kind of results it enjoyed last year and will head to Spa next weekend for the Belgian Grand Prix with just seven points on the board.

With the team's financial situation having been well documented in recent weeks, much of the focus within the Hinwil-based squad has been on trying to finalise agreements to allow the team to move forwards.

Looking towards the action on-track however, Kaltenborn said she felt things were looking up but refused to set any targets about what to expect in the second half of the year.

"It's been a disappointing first half because we clearly came here with high expectations which were based on last year's performance and in view of the changes from last year to this year I think we had good reason to believe that," she told ESPN. "We somewhere went wrong, we've seen the result now and now we're working our way up again slowly but surely.

"We're in the middle of a season right now and you should not underestimate any team. Last year it looked like we were a safe bet for sixth position and we were going for the fifth and eventually at the last race it wasn't even sure where we were, so I think we should really be prepared that until the end nothing is really decided in this part of the championship."
