Heikki Kovalainen's name has been linked to several teams in the past few weeks, but the Finn insists it's just "rumours".
The 30-year-old was last week mooted as a possible replacement for Lewis Hamilton at McLaren should the 2008 World Champion decide to join Mercedes.
This week it's the turn of Ferrari with Finnish media reporting his manager held talks with the Italian outfit's bosses at Maranello.
However, Kovalainen says it is just speculation at this point and also revealed he is yet to hold contract talks with Caterham team principal Tony Fernandes.
"There is no news for me to comment on at the moment," he told Sky Sports in an exclusive interview. "They are just rumours and there seems to be all sorts of rumours going around, so I don't really pay much attention to those.
"I will talk to Caterham at some point, I'll speak to Tony and see what the plans are and after that talk with my management to see what we will do next year. My main focus is on my performance and to make sure I keep performing well, and these other things will sort themselves."
With the European leg of the 2012 F1 season done and dusted, Kovalainen and Caterham are off to Singapore this weekend.
Caterham's CT01 will sport a new front wing and the Finn is hopeful it will edge them closer to the midfield runners.
The Leafield-based squad had high hopes of not only giving some of the established teams a run for their money this season but also set their sights on scoring their first points.
Although they are yet to achieve either of those targets, Caterham are determined to push hard until the end of the season and Kovalainen is optimistic that the new wing will help them to close the gap further.
"We will have a new front wing," said.
"It is slightly different and should give us a straightforward performance increase, some more downforce and hopefully makes our car a bit quicker. Other than that, there is nothing major, just a few small updates. The front wing is the main thing we will have this weekend.
"Singapore is a totally different circuit to Monza and Spa - it requires a different setup and the conditions are different. At the moment it is a bit of a guess how everyone will perform there, but certainly for us Monza was better than Spa.
"I know there has been a lot of data-analysing going on since those events, trying to understand why our Spa performance was not very good and then Monza was much more like normal and I think we understand the main issues. Hopefully, if we experience any problems this weekend we can react to them."
