A furious Lando Norris blamed world champion Max Verstappen for the collision which ended both their hopes of winning a thrilling Formula One Austrian Grand Prix on Sunday.
Triple world champion Verstappen looked to be coasting to a third win in three races but an unusually slow pit-stop from Red Bull on their home track opened the door for McLaren's Norris.
The Briton tried to get past the Dutchman three times and on the last bid on lap 64 of 71, their wheels clashed and tyres blew. Norris had to retire while Verstappen, blamed by the stewards for the shunt and handed a 10-second penalty, came home fifth. Mercedes' George Russell sheepishly took the chequered flag.
Norris is friends with Verstappen but there will now be tension heading to next weekend's British Grand Prix where the Silverstone crowd will be very much behind the McLaren man, in contrast to the throngs of Red Bull fans in Austria.
"I'm just disappointed. I expected a bit more from Max," Norris told reporters. "Careless."
When asked if he expected an apology, the 24-year-old added: "It is for him to say something."
It was even more bitter for Norris given Verstappen's fifth place meant he extended his lead over his friend at the top of the standings to 81 points.
Verstappen denied that he had been "moving under braking" but added: "It was a shame what happened. He dived bombed from behind and it is hard to defend. Our race was very bad, from strategy to pit-stops. Too slow really. There was no balance in the car."
An apology to Norris though is not coming immediately.
"That was obviously intense. We will talk about it, but maybe not today," smirked Verstappen.
