"I'm not nervous," the Austrian told Bild newspaper. "Don't forget that we still have Vettel."
Speaking to Finnish newspaper Turun Sanomat on Monday, Raikkonen's manager Steve Robertson admitted the current Lotus driver is not moving to Red Bull.
"The negotiations with Red Bull were not successful and ended some time ago," he is quoted as saying.
Robertson did not mention whether Raikkonen would stay at Lotus in 2014 or return to Ferrari, but he admitted it is 99.9 per cent sure the 33-year-old will still be on the grid next year.
