Kimi Raikkonen's plans for a one-year sabbatical from Formula One lasted less than 24 hours before his manager suggested he might be open to offers from Brawn's new owners Mercedes.
Steve Robertson told the autosport.com website that the Finn, who failed to reach a deal with McLaren after leaving Ferrari, was not 100 percent certain to be absent next year.
Robertson says if Mercedes can offer Raikkonen an opportunity that gives him confidence he can win races and the championship, then there is always a possibility.
Brawn won both titles this year with Britain's Jenson Button, who has now departed to McLaren.
The champions will compete as Mercedes next season, with Germany's Nico Rosberg expected to be one of their drivers.
Speaking in Macau, Robertson says Raikkonen's position was not all about money.
He says there aren't many teams that appeal to the Finn because he is honest when he says he has to have a car that can win.
Robertson said earlier this week that McLaren could not afford Raikkonen and the driver was going to compete in the World Rally Championship before aiming for a return to Formula One in 2011.
