Ferrari would have clinched the constructors' world championship in Brazil even if McLaren had not been excluded amid the espionage affair.

The Maranello based team's boss Jean Todt said he was aware of the detail in discussion with reporters at Interlagos on Sunday.

"I knew that it was always said we had won only because of the decisions (and) not because of the sporting results," the Frenchman said.

"So I will say that is better that it is (also) done on the normal side," he added.

McLaren was commandingly leading the constructors' standings when the World Motor Sport Council disqualified the team.

But Ferrari's one-two at Interlagos, which also clinched the drivers' title for Kimi Raikkonen, would have put Ferrari over the line by a single point (assuming the Hungarian points deduction had not been overturned) even if McLaren had still been eligible to score points.

"To be very sincere, I knew we had won, but I was counting," Todt said.
