Ricciardo has argued that Vettel moved in front of him under braking, despite such moves recently being outlawed.
Ironically, Vettel has been one of the more vocal critics of Max Verstappen, who has been making similar moves all season.
"He did what everyone has been complaining about – moving under braking," Ricciardo said after the race.
After Verstappen was handed a five second penalty, Vettel moved up a place into the podium places, but Ricciardo was fuming with the decision.
"He's smiling now but for me he doesn't deserve to be on the podium," he said. "He kept on closing the door under braking and in the end I had nowhere to go."
