Sauber pair Kobayashi and Perez say team must iron out errors in second half of 2012

That is the view of its drivers Kamui Kobayashi and Sergio Perez, who both believe that the outfit can deliver a lot more in the second half of the campaign than it did in the first.

Kobayashi said: "Overall we have done a good job and achieved great things. The team built a very good car with an excellent performance.

"Since the beginning of the season we have been competitive on most tracks, and this means we can be confident for the remainder of the season.

"The downside so far has been we definitely missed some opportunities for some more great results. Too often we didn't manage the weekend perfectly. If we can improve there, a lot will be possible."

Although Perez has delivered two podium finishes for the team this year, the outfit has seen other opportunities slip through its grasp - like with the Mexican's puncture on the first lap in Spain, and his steering problem in qualifying in Monaco leaving him unable to fulfil all that had been hoped.

Perez added: "We need to be more efficient and I want to contribute to that. It is not that our performance was not consistent, but we didn't always get the things right and also we have been unlucky sometimes.

"We have to get everything together and make the most out of what we have. The car is quick and for me my first victory would be a dream come true."
