Former F1 World Champion Nico Rosberg has insisted Lewis Hamilton must apologise to George Russell following their collision in Spanish Grand Prix qualifying.
Russell had moved out of Carlos Sainz's way in between the final two corners late into Q2 but wound up for his final attempt at a flying lap just in front of teammate Hamilton.
The seven-time World Champion closed in with the slipstream and pulled to the outside of Russell, only for the gap to close and contact initiated - Hamilton losing his front wing end-plate.
Russell failed to reach Q3 and will start 12th whilst both Mercedes drivers have been summoned to the stewards with the incident under investigation.
"They had traffic to start the lap," explained Rosberg for Sky Sports F1.
"Lewis decided to go for it and try to overtake and George didn't see him at all. It is kind of unfortunate, but I think there will be some serious discussions."

George's lap would have been 'ruined'
Russell apologised over team radio for his part in the incident but Rosberg believes former teammate Hamilton should reciprocate the sentiment.
"George apologised, which I think is right, but Lewis also needs to apologise," said the 2016 World Champion.
"If Lewis goes through, George's lap is done because Lewis is right in front, George would be right behind and his lap ruined.
"So also Lewis would need to apologise."
