Glock says 2008 goals achieved now

"I am happy with the job I did; I made no mistakes and fourth is a good result," said Glock, who has scored 20 points and is ninth in the championship standings.

"It was quite tough out there in these conditions and with such a bumpy track the car was not very comfortable to drive; I am sure I will feel the effects tomorrow.

"My goal at the beginning of the year was to score 20 points this season so I am very satisfied to achieve that with three races still to go."

The German said, however, that he will not relax as Toyota are still fighting for fourth place with Renault.

"I am fighting for the team to help them finish fourth in the constructors' championship and we were a bit unlucky with that today, but congratulations to Fernando, who did a great job. Now we will go to Fuji and aim to recover the lost ground," he added.

Teammate Jarno Trulli's day ended in disappointment after suffering a hydraulic failure when he was set for a point-scoring finish.

"The race was going pretty well, I was on a one-stop strategy and I made a good start," he said. "After the safety car, I was one of the quickest on the track and I led the race for several laps. But in the end a weekend which started pretty bad has finished even worse.

"I had a hydraulic problem when I would have finished in fifth; that would have been good points from a weekend which has been quite hard for me. I am exhausted because I am so disappointed.

"I have been fighting really hard and doing a good job but when that bad luck comes you can't do anything about it. I think I am owed a lot of good luck after that."
