Sauber boss Monisha Kaltenborn says she feels the team is close to being able to celebrate a race victory after Sergio Perez secured his third podium finish of the year at Monza.

The Mexican put in a fine drive to storm through the field to finish second behind Lewis Hamilton, making the most of his strategy which meant he started on the harder compound tyre before switching to the mediums for the run to the flag.

That saw him chase down the cars ahead to finish just 4.3secs behind winner Lewis Hamilton, adding to his podium finishes earlier in the year at Sepang and in Montreal.

Speaking following Monza - a race where Sauber hadn't expected to be in the mix - Kaltenborn said she felt the team was close to being in a position to now challenge for a victory, although she admitted that everything would need to fall into place for it to be possible.

"It's very difficult to say (that we will win), because so many things have to be right to win a race," she was quoted by ESPNF1. "I think we are very close to it, and all we can do is just make sure that we don't make mistakes on the track and then I'm sure it will work out.

"I think we've been seeing throughout the season that this car actually is a very good car. And of course when you bring these sorts of results home then it proves it even further, so for us we continue to be convinced that it's a very good car and now we hope that the packages we still have for the overseas races are going to kick in the way we expect them to and then I think we can still keep our level of competitiveness quite high."

Kaltenborn added that the result would hopefully go some way towards helping Sauber to secure more sponsorship for the 2013 season.

"I think with this podium, it will make a lot of people believe that our level is quite good this year, which is also the basis for next year's car," she said. "Performance is all what potential sponsors look at and I do hope that this will give us more boost."
