USF1blog.com reported back on September 20th that Kimi looks to be heading to McLaren for 2010, but this weekend Raikkonen has joked that he could race in NASCAR  in 2010 should he so desire – as he remained adamant on the eve of this weekend’s Brazilian Grand Prix at Interlagos that he still has ‘no plans’ beyond the end of the current Formula 1 season.

The 2007 world champion is being dropped by Ferrari – for whom he has driven since that title-winning campaign – at the end of the year in favor of Fernando Alonso, the man Raikkonen pipped to the laurels by just a single marker two years ago.

Since the paddock’s worst-kept secret was finally officially confirmed earlier this month, the 18-time Grand Prix winner’s name has been linked with Renault, McLaren-Mercedes – for whom he competed at the highest level from 2002 to 2006, triumphing nine times along the way and arguably being unlucky not to clinch the crown in 2003 and 2005 – and Red Bull Racing, with Toyota Motorsport President John Howett also having made little secret of his desire to secure Raikkonen’s services.

However, despite time pressing on and seats beginning to fill, the 29-year-old – who will turn 30 on qualifying day in Sao Paulo – insists he has yet to make any decisions regarding next season, when it has similarly been suggested that he might further indulge his nascent forays into rallying by way of a more full-time switch, or even follow in the wheel tracks of fellow former Grand Prix stars Jacques Villeneuve and Juan Pablo Montoya by heading across the Pond to NASCAR, a mooted destination for ‘Singapore gate’ protagonist Nelson Piquet Jr too.

USF1blog.com recently took an in-depth look at the 2010 drivers market, and we are now hearing that Kimi Raikkonen has signed a preliminary “outline agreement” to kick off a second tenure with McLaren beginning next season.  The Mirror cited “paddock sources” in claiming that Raikkonen is prepared to vacate his contracted Ferrari seat in 2010, but only if the Italian outfit pays his salary. It is estimated that Raikkonen’s 2010 Ferrari contract is valued at nearly $49m.

The 29-year-old Finn, who raced with the woking based outfit between 2002 and 2006, must first reach an agreement with Ferrari, with whom he is under contract for one more season.

The report also said the news ties in with Nico Rosberg’s link with Brawn and the Brackley team’s burgeoning relationship with Mercedes-Benz.

Mercedes was said to be pushing for Rosberg to replace Heikki Kovalainen at McLaren, but may now have resolved to push the German driver to Brawn and increase its involvement with Ross Brawn’s team.

This of means, of course, that the fate of Barrichello and Kovalainen are still up in the air for next season.
