May 22 (GMM) Kimi Raikkonen has admitted he is weighing up two offers to remain in Formula One beyond 2013.

In the wake of his impressive return to the sport, the Finn's two-year contract with Lotus is now expiring.

The Enstone based team clearly wants to retain the 33-year-old former world champion, who has thrived under Lotus' laid-back regime.

But team owner Gerard Lopez admitted to PA Sport news agency this week: "If he could find a better car somewhere else, and he had an option to go there, then I'm sure he would consider it."

Raikkonen's other option could be Red Bull, who are not yet committing to Mark Webber beyond the veteran Australian's 2013 deal.

When asked how many options he has for 2014, former Ferrari and McLaren driver Raikkonen told Italy's Autosprint: "It depends.

"I would say that I have two, but in F1 you never know exactly.

"I've been here (in F1) long enough to know that the only thing that matters is finding the right situation for yourself," he answered, when asked how he will come to his final decision.

Steve Robertson, Raikkonen's long-time manager, said it is obvious the cool Finn - nicknamed 'the iceman' - is the hottest property on the driver market at present.

"Kimi has done a brilliant job with Lotus so it's no secret that, at the moment, he is the hottest driver available for next year," he told Finnish newspaper Turun Sanomat.

"You know what a good job a driver is doing when a team (Lotus) starts talking so early about next year," added Robertson.

"I am not saying if there are more teams interested (in Raikkonen) but, for sure, a driver as competitive as Kimi is right now is always very much in the attention of all the top teams," he said.
