He won the Monaco Grand Prix despite an MGU-K failure impressively from title rivals Sebastian Vettel and Lewis Hamilton, but Daniel Ricciardo is set to be brought back down to earth with grid penalties for the Canadian Grand Prix.
Red Bull technical director Adrian Newey believes that Ricciardo could be set to pay the price in Montreal for his daring win last time out in Monaco.
"We could be suffering some quite big penalties," he said.
"We are only allowed two batteries etc and the system in that sense seems completely wrong.
"He will definitely be taking some penalties in Montreal, we haven't heard at the moment just how many.
"One of the things there is whether the battery was damaged or not in Monaco, so until we know that from Renault we don't know exactly what we're facing."
