Daniel Ricciardo has fuelled speculation he could race for Caterham next year, after admitting it was unlikely he would be joining Scuderia Toro Rosso's line-up.
As AUTOSPORT revealed earlier this month, Red Bull chiefs have held discussions with Tony Fernandes about the possibility of the Australian racing at his outfit in 2012 if Jarno Trulli is not kept on.
Although no decision has been taken, Ricciardo confirmed on Tuesday that there was a possibility of a move to Caterham.
Speaking to the West Australian newspaper, Ricciardo said: "At the moment it seems like Toro Rosso are going to stay with who they've got.
"It wasn't put down 100 per cent, but it was the wording I was making out. There's a good chance if I'm on the grid next year it's going to be with another non-Red Bull outfit, but I guess the good news is I'm still contracted by Red Bull. They've agreed to continue with me."
When asked specifically about the Caterham rumours, Ricciardo added: "I would like to say there's a chance, but at least for me that's probably all it is for now, just a chance.
"It would be a step up from this year, so it's not really a bad thing. I doubt they'll still be able to fight for points next year. They'll still be towards the further end, but I think they're progressing well.
"If (Heikki) Kovalainen was to be my team-mate, it's someone very good to measure up to. He's won a grand prix before and he's smashed Trulli this year."
