Taku not expecting Canadian repeat.

Takuma Sato insists that he isn't expecting a repeat of his Canadian Grand Prix heroics this weekend as the Formula 1 World Championship heads to Indianapolis for the second of back-to-back races.

The Super Aguri ace produced one of the drives of the day in Montreal last time out as he took the best finish to date for the second year team - passing double champion Fernando Alonso in the closing stages en-route to a fine sixth place.

Adding to the point secured earlier in the year in Spain, the result boosted morale within the squad heading to Indy - although the Japanese driver admitted that a repeat this weekend won't be easy.

"Our team feeling is absolutely fantastic," he said. "Canada was an outstanding result for our team in the last one and half years. Obviously, it was a difficult race, so many things happened and such an eventful race and given the choice, I think everybody has got a chance, and everybody had slight difficulty, but at the end of the day, we made the right call. It was so exciting to race on the last few laps. I got my position back which was really exciting, I am very, very happy with that.

"Personally I have great memories of Indianapolis. It's such a nice feeling, there's such a great momentum from last week and two consecutive races are always logistically difficult but from a driver's point of view, it's nice to have a race again straight away. I think it's going to be incredibly difficult to repeat what happened in Canada but I'm confident that our team prepares the best we can and hopefully we will have a strong weekend."
