Talking to the reporters in the Montreal paddock on Tursday, Romain Grosjean revealed he expected an apology from the 17-year-old Max Verstappen who crashed after slamming into the rear of his Lotus in Monaco.
It follows Verstappen's post-race declaration that he was "brake-tested" by Grosjean.
"Even this morning in the press conference he was saying 'I'm going to drive the same way'," Grosjean said on Thursday.
"We went to the stewards after the Grand Prix and he could have said 'I'm sorry' but he did not," he is quoted by RMC Sport.
"As I said, he is very talented," said Grosjean, "but it would not cost anything to tell me 'I'm sorry, I braked too late'."
There was also a fiery exchange between the youngster and Felipe Massa in the FIA press conference, following 34-year-old Massa's criticism of Verstappen.
"Well, everybody can have their opinion, that's the first thing," said Verstappen.
"I'm focusing on Canada right now and maybe you (Massa) should review the race from last year and see what happened there," he charged.
Verstappen was undoubtedly referring to Massa's huge Montreal crash in 2014, when he hit the rear of Sergio Perez.
"I think it was a little bit different, no?" Massa hit back. "I was on the side and he (Perez) moved the car on braking so ... I don't think Grosjean moved the car on braking, no?"
