McLaren star Kimi Raikkonen has dismissed a report claiming he has agreed to drive for Ferrari in 2007.
Germany's Bild newspaper claimed the Finn had signed a pre-contract agreement with Ferrari, with Michael Schumacher moving the other way.
But Raikkonen said: "As I have said on a number of occasions this season already when asked about the rumours, I am completely happy with my team."
McLaren and Ferrari also denied there was in anything in the report.
Citing a "completely secure source", Bild said that the first talks over Raikkonen took place last year with parties discussing an advance contract in February and March before agreeing terms in May.
But Raikkonen, who has won five races this season and is second in the standings behind Fernando Alonso, stressed he has no intention of leaving McLaren.
"I don't think there is any doubt that we have the fastest package on winning races, I'm still challenging for the world championship, the team is fantastic and I have a great relationship with everybody here so why would I want to consider changing?
"Surely I am in a position that most drivers in Formula One want to be in."
McLaren team boss Ron Dennis added: "We anticipate long-term relationships with both Kimi, who is in his fourth season with us, and Juan Pablo (Montoya).
"Consequently the team is not in discussion with any other driver, including Michael Schumacher about a possible team McLaren-Mercedes race seat."
Ferrari spokesman Luca Colajanni said: "We already have two drivers under contract for the 2006 season.
"It is too soon to start talking about the 2007 season. We have not made any commitments with anybody for 2007."
World champion Schumacher will be joined at Ferrari by Brazilian Felipe Massa next season after Rubens Barrichello departs to BAR.
