As the speculation increases about who will replace Mark Webber at Red Bull next season, former champion Kimi Raikkonen remains unsure if he will stay at Lotus.
Webber announced last month he is quitting Formula One at the end of the season to race sports cars for German manufacturer Porsche, and there has been a guessing game since over which driver Red Bull will pick to compete alongside three-time defending champion Sebastian Vettel.
The 33-year-old Raikkonen is tipped as a favorite. The 2007 F1 champion is yet to commit his future to Lotus and says “I have no idea what will happen”.
Australian driver Daniel Ricciardo and Frenchman Jean-Eric Vergne both race for Toro Rosso — Red Bull's sister team — and are reportedly among the contenders.
