Red Bull's motorsport advisor Helmut Marko left Sepang 400 euros richer – by betting on a Ferrari.
Germany's Sport Bild reports that Marko put his money on his former protege Sebastian Vettel in an internal paddock bet, rather than his own drivers Daniel Ricciardo and Daniil Kvyat.
"I knew that Sebastian could do it," he said. "You could see it as early as Friday practice."
Although Vettel left Red Bull after a fallow season last year, Marko says it was obvious the 27-year-old had not lost his quadruple title-winning talent.
"He did not forget how to drive in one year," Marko said. "He just could not drive our car as he needed to.
"Maybe people will realise at last that it was not our car alone that gave him those four titles."
Marko also hinted that Red Bull might be missing Vettel's technical input already.
"Today we had extreme problems with the brakes," he added. "After Sebastian left we changed to a manufacturer that he never liked, but we will change back now."
