Following the confirmation that Sebastien Bourdais will remain with Toro Rosso in 2009 - a move which was announced on the driver's website and not by the Faenza-based outfit - Takuma Sato's manager Andrew Gilbert Scott has issued the following:

"I am extremely disappointed that Scuderia Toro Rosso has not chosen Takuma to race for them in 2009.

Taku had showed tremendous speed and commitment during the three tests he did for the team and I believe he proved to be the faster driver.

Unfortunately however the team made no secret about the fact that they would need the drive to bring a substantial amount of funding to the team to secure the drive. We have all been working very hard and have been able to attract a significant amount of sponsorship to support the team but unfortunately it was obviously not enough to secure the drive.

We would like to thank our loyal and new sponsors and also many Takuma fans for everything they did to try to help secure the Toro Rosso drive for Taku. We will now be looking ahead for the next opportunity."

Sato added: "I am not sure what my future holds, I will be discussing with my manager what our next steps should be. However, I strongly feel that I have unfinished business in F1 and that I still have a lot to give. I am determined to stay in top level motorsport and I will be fully focused on making a return to F1 as long as any opportunity is there.

I want to thank all my supporters who have been absolutely fantastic with their loyalty, I will always remember these fantastic relationships we have built and hope we can one day repay this support."
