After Red Bull driver Daniil Kvyat was to blame for Ferrari driver Sebastian Vettel retiring early, Mercedes chairman Niki Lauda has slammed the Russian's reckless behaviour.
During the early stages of lap one at the Russian Grand Prix, Kvyat rammed into the back of Vettel at turn two and then did it again on turn three.
Adding to the controversy, Vettel was sent flying into Kvyat's own teammate Daniel Ricciardo, something Red Bull wasn’t too pleased about.
Lauda, a three-time World Champion, praised the Ferrari driver's composure after the incident but did add that the young Red Bull driver was completely out of order.
"If I were Vettel, I would kill him," he told Sky Sports. "Horrible. He can not drive all over the place with utter silliness.
"Vettel did everything alright. Kvyat crashed into him from behind. He couldn’t have done that sillier and more annoying."
Echoing Lauda's words, Ferrari team principal Maurizio Arrivabene thought it was unacceptable that Kvyat hit his driver twice in such a short space of time.
"He hit him (Vettel) two times. You can accept it for the first time, but not for the second time," Arrivabene continued.
"He was penalized, but it is not acceptable."
