Raikkonen looking to build upon early form across second half of 2012 season

The 2007 world champion, who has finished on the podium three times since he came back to Formula 1 following a two-year spell in the WRC, says that while he is pleased with the results he has achieved so far with Lotus, he is also frustrated by the knowledge that he could have done even better.

"You always prefer to be higher up and if you would have told me before the season that I would be on the podium a few times and I had this many points I probably would say that yes that's great," he said.

"But then of course you get there and you know that with certain things we could have done better and we would probably have had better results so then you are always a bit disappointed.

"But no I am still happy and as a team we are in a pretty good position, but still we could have done better, so it is just the fact that we haven't achieved what we probably should have achieved."

Raikkonen added that he is still working towards a better feeling in the E20 and admitted that disrupted race weekends are hindering him from achieving that goal.

"If you make a small error somewhere or have a small issue at a certain point of the weekend then it can easily cost you a lot of time," he said. "It looks like a small thing but it might make a big difference in the end.

"It is difficult to always get the perfect weekend, it's not the easiest thing.

"We have to still find on the set-up side something that we are 100 per cent happy with, and we are looking for it and we have some ideas. But every time when it's wet like this we have to wait and it's not so simple to say okay we'll try this and this. The weather can change or you have a small issue and then you cannot do anything.

"We just have to be patient and try to get as good a result as we can and try to just work on the small details that we have to improve."
