Charles Leclerc demanded answers from his Ferrari team after a strategic error resulted in him qualifying 16th for his home Monaco Grand Prix.
Ferrari chose not to send Leclerc out for a second run at the end of the first session and he was knocked out – by his own team-mate Sebastian Vettel.
Leclerc said: “I asked whether they were sure [I was safe]. They said we think we are.
“I said, ‘shouldn’t we go again? I need an explanation.”
The result means Leclerc’s race is already effectively a write-off, as overtaking is close to impossible around Monaco.
“Hopefully [there will be] some rain,” he said. “If it is dry, it will be boring. I have to take a lot of risks, even risk to crash, but it’s all I can do to take some risks.
“I’m very disappointed today. Hopefully tomorrow [in the race on Sunday] will be better but I doubt so if it’s dry.”
Ferrari were struggling in the first session and after the first runs Vettel was not quick enough to get through in the fastest 15 drivers without going for a second run.
But Ferrari felt Leclerc would be all right, despite clear signals that he was at risk.
