Mercedes boss blasts 'brainless' Hamilton and Rosberg
Furious Mercedes boss Toto Wolff described a last-lap collision between teammates Lewis Hamilton and Nico Rosberg at the Austrian Grand Prix as "brainless."
Hamilton won the race after a dramatic crash with championship rival Rosberg.
Rosberg appeared on course to claim his sixth victory of the season, but crashed into Hamilton as the Briton attempted to pass his Mercedes team-mate around the outside of turn two.
Rosberg sustained damage to his front wing in the incident, allowing Hamilton to assume the lead and subsequent victory, while he could limp home only in fourth.
The collision between the championship protagonists enabled Red Bull's Max Verstappen to claim second with Ferrari driver Kimi Raikkonen taking the last spot on the podium.
Wolff described the collision as "brainless", adding "it could have been a double DNF. At the moment I do not know what I will say (to Hamilton and Rosberg)."
Wolff and Mercedes chairman Niki Lauda both said Rosberg had suffered a brake problem.
"It was not funny to watch it," said Lauda. "I know that Nico had a brake problem."
Rosberg appeared to point the finger at Hamilton for causing the collision.
"I'm absolutely gutted," he said. "It's unbelievable.
"We were battling and I was struggling a little bit with my brakes.
"I gave Lewis a chance. I had the inside position and I went a bit deep in the corner and I was very surprised that Lewis turned in and that caused the collision."
Hamilton was booed on the podium as he celebrated.
"I don't know why [they're booing]," Hamilton said. "It's not my problem, it's their problem".
