Lotus driver Kimi Raikkonen has admitted he is disappointed not to have won a race so far this season.

Raikkonen, who has returned to F1 this year following two years in the World Rally Championship, took his third podium of F1 2012 in Valencia last weekend, but while he concedes he would have been happy with that pre-season, now he 'wants more' given how competitive the Lotus E20 has been.

"If you asked me before the start of the season whether I would be happy with podiums I would have said yes, but now I've had some good results, I want more," explained the Finn.

"In the last few races the results haven't been as strong as I've wanted. We've finished well but I'm disappointed not to have a win yet. We just have to get everything together and I'm sure it can come."

Raikkonen will get his next chance to try and win a race at Silverstone in just over a weeks time and he is looking forward to the British Grand Prix.

"It's always such a good feeling going to Silverstone. It's a great place to race. I have a long history there," he continued

"It was the real base for the start of my international racing career in Formula Renault in 1999 and 2000. Since then I've always enjoyed racing at Silverstone. I don't know why; there must be this nostalgic feeling that I have every time we go there.

"When you win in Silverstone, it gives such a good feeling. You have to get everything exactly right.

"I won there in Formula Renault and then with Ferrari in 2007. It would be fantastic to win again there, especially with the factory just down the road. I'm sure we would have some fantastic celebrations."
