Sebastian Vettel says that he never for a moment worried about the controversy surrounding his pass on Jean-Eric Vergne on lap 4 of the Brazilian Grand Prix. After Ferrari complained, the FIA ruled quickly  that there was a delay between the light and the corner worker waving the flag. 

"To be honest, I never wasted one single thought that an irregularity was involved from my side. Even if it was an eventful race I definitely saw all the flags - and their colours!

"But believe it or not I knew since the checkered flag that there was not a single movement wrong from my side," said Vettel. 

He also said that he only learned about the controversy after the race when Christian Horner told him.
