Rubens Barrichello has admitted he is interested in returning to formula one.
Out of the sport since losing his Williams seat in 2011, the hugely-experienced Brazilian has reportedly put together a sponsorship package and is in the running to drive for Sauber next season.
Speaking in Korea, the Swiss team’s boss Monisha Kaltenborn said "let’s see" when asked about the speculation.
And Barrichello, 41, wrote on Twitter: "Lots of things have been said this week about a possible F1 return.
"The truth is: if there is an opportunity, I’m in."
His friend and compatriot Felipe Massa, who is also fighting for a seat in 2014, said he would welcome Barrichello back to F1.
"He cannot stay at home," smiled Massa, referring to the fact Barrichello is now a commentator for Brazilian television Globo.
"Hopefully it will be possible for him to return, because it has to do with the financial side at Sauber," he told Totalrace.
