Nico Rosberg says his future plans have been thrown into chaos by the plans by Formula 1 teams to launch a breakaway series.
The German driver has been evaluating his options for 2010 - having most recently been strongly linked with a switch to BMW Sauber.
However, with his Williams team one of only two current teams that has lodged unconditional entries to next year's championship, Rosberg now faces an extra dilemma in terms of needing to choose which category he wants to compete in.
"It makes it rather complex," admitted Rosberg about his future plans. I don't know what the situation is. I mean they don't have a second series yet. They have just made a decision not to race in the FIA F1 world championship. It is a bit of a mess really at the moment and it makes it very difficult. We will have to wait and see."
Rosberg believes that the split between the Formula One Teams' Association (FOTA) and the FIA has turned the sport into a 'big mess.'
"It's a pity I guess," he explained. "It's really quite a disastrous situation for the whole sport at the moment. I can't believe it has come to that actually. It's very strange."
"I think that the FOTA teams have now decided 'we are going, it is now in the hands of the FIA, either they make a change or we are gone'. So now it is up to the FIA to see if they just stick to what they want and have F1 without any of the FOTA teams next year."
"I have even heard that they may sue the teams, so it is just a big mess really. I wish in some way they might find a way together so that we can continue racing like this year which has been fantastic. But it is looking quite unlikely to be honest and that is a pity."
