Although his future at Williams remains clouded, Bruno Senna has revealed that his sponsors are still prepared to back him.
In Abu Dhabi for this weekend's third-last race of 2012, the Brazilian admitted he is still waiting for Williams to decide its lineup for next season.
"Whenever you're not confirmed by the end of the championship it gets more difficult," he told Totalrace, "because the further you get, the fewer options there are."
"Each team has different priorities, but my Brazilian sponsors are very pleased with this year's results in all aspects and understand that this is not a project for just one year," he said.
He would not be drawn on rumours Force India could be an alternative for him in 2013.
"That they say that is obvious," said Senna, "because it's one of the only teams that has a seat, so it's easy to say.
"We are focused on staying in Williams," he insisted.
