Verstappen created a huge stir at Interlagos by disobeying a team order to let Perez into sixth place on the last lap, which would have been a huge boost to the Mexican's quest for second place in the world championship.
Horner immediately came onto the team radio and apologised to Perez. However he said nothing to Verstappen, contrary to his usual practice of congratulating the Dutchman on his race.
