Kimi Raikkonen refused to be drawn on his future amidst reports that Red Bull Racing want him as Mark Webber's replacement.
The Finn had had a successful return to Formula One and is currently second in the Drivers' Championship behind Red Bull's Sebastian Vettel.
But whether he's considering joining the German next season, Raikkonen isn't saying.
"I have no contract for next year - that much is true," the Finn told the official F1 website. "But further than that, I don't want to discuss the matter.
"I want to do well this season and everything else will fall into place."
Pressed as to what his reasons may be for considering a move or even staying at Lotus, he said: "I haven't thought about all that yet - I feel good here.
"But yes, there are many things that are undecided and there is still a long way to go this season, so let's see how things unfold.
"We will see pretty significant changes when teams switch to their 2014 car development - and then it will be interesting to see what is going on."
However, should he opt for a move to Red Bull, Raikkonen may have to deal with team-mate issues such as what Mark Webber is experiencing.
Asked about the prospect of teaming up with Vettel, who Raikkonen is friends with, the Lotus driver said: "I don't know. These are not the things that I think about right now."
