Trulli has no doubts about his future

The Italian signed a three-year contract with the Japanese manufacturer last season and has had the edge over teammate Ralf Schumacher throughout this campaign.

Question marks about his position emerged prior to Brazil, however, when team principal John Howett refused to confirm Trulli's place was guaranteed.

Howett told the latest issue of Autosport magazine: "Is his 2008 seat secure? That's a difficult question to answer. I guess if his performance is good enough he'll be in the car."

Trulli, however, said he has had no indication from the team that his place is under threat. He also denied further rumours that he was going to test for Spyker next month.

"I have a long term contract," he told autosport.com. "I have a contract which I want to respect perfectly because I am putting a lot of effort in to make this team improve.

"This talk about my future is news to me. I just heard it now."

When asked if Howett or other senior management at the team had talked to him about his future, Trulli said: "No one. I don't need to talk with anyone. The team hasn't told me anything."

Trulli said his focus was on helping Toyota make the improvements they need to become regular challengers for podium finishers once again.

"Now I just want to push very hard for the winter," he said. "I want to make sure we have a good car for next year.

"So I will probably go to the factory as soon as possible, try to push people and motivate them and try to get them really in the right direction for next year."
