Sergio Perez has admitted he needs to up his game in qualifying and he will be concentrating on doing just that in Germany this weekend.

The Mexican has failed to deliver on a Saturday in the last four races and hasn't started better than 15th - and while he did still come back and score points with an excellent second place in Montreal and a ninth place in Valencia, he is more than conscious that he is making life difficult for himself by not starting higher up the grid.

"For us it remains important to do better in qualifying, so our Saturday performance is what we have to focus on first," confirmed the Sauber driver ahead of the tenth round in the F1 2012 World Championship. "Our car is quick and if we could just get everything right this time we have good chances for a nice race result.

"In Hockenheim I especially like the stadium part that is, driving wise, challenging and has a great atmosphere.

"Also for me personally it is nice to go back to Germany after I lived there for two years in the early stages of my career. The first year - 2005 - was in Vilsbiburg in Bavaria and then a second year in Berlin."

Team-mate Kamui Kobayashi will also be after points, although he admits that they still need to properly assess the latest updates to the C31.

"We are not totally sure how the updates we took to Silverstone work, as we haven't really been able to confirm these in practice in dry conditions. Maybe we need to do some more fine-tuning on these, so it will be interesting to see how this happens in Hockenheim," he explained.

"I think our car performs well on all the circuits - high speed or slow speed ones - so I am not worried about our performance. We shall just focus on trying to get our best result.

"I like the circuit in Hockenheim and have quite a lot of experience there from Formula Renault, Formula 3, GP2 and F1. Usually at the time when we are there for the Grand Prix it is quite hot.

"I am very excited about racing in Germany, which is not too far away from Hinwil, so is a kind of home race."
