Kimi Raikkonen has suggested he could walk away from Formula One after losing his place
at Ferrari to Spain's Fernando Alonso.
The 2007 world champion, preparing for this weekend's Japanese grand prix, says he hasn't yet decided if he wants to continue in formula one, and although he's been strongly rumoured to return to McLaren, team sources say nothing has been agreed.
Raikkonen drove in a round of the world rally championship this year and that could be another avenue to explore.
