German Grand Prix: Kimi Raikkonen complains final stop cost victory

Kimi Raikkonen believes he may not have required his final pit stop -- and that it could have cost him victory in Sunday's German Grand Prix at the Nurburgring.

The Lotus driver stopped for a set of softs 10 laps from the finish and, despite reclaiming second from his team-mate Frenchman Romain Grosjean, he finished one second behind the victorious home hero German Sebastian Vettel of Red Bull.

Raikkonen said: "I could run longer and we had to think about if we should try to run until the end.

"But I had massive problem with the radio. I could hear the team but they couldn't hear me, apart from at two corners.

"I wonder if we should have gone to the end as the tyres were OK."

Raikkonen agreed with Vettel's suggestion that the lead would have changed had the race been any longer.

"It's hard to know what would have happened in the next two laps," said the Finn.

"We had good speed. I think we would have had a big fight anyhow and probably passed him.

"We tried everything we had and failed to win, but I think for the team we had a good race. We'll keep trying."
