Leclerc's first home race driving a Ferrari came to an early end, after a disappointing qualifying blunder by the Scuderia meant that the Monegasque started from down in 15th position.
Leclerc made the same move on Nico Hulkenberg at Rascasse, but misjudged the move and clipped the inside barrier, which punctured his rear tyre. This in turn destroyed the floor of his SF19 as it disintegrated, which led to the team retiring the car.
The move also caused damage to Nico Hulkenberg's RS19, which compromised the German's pace during the race.
“Charles was too aggressive. He came quite far back and I didn’t leave much of a gap anyway,” Hulkenberg told reporters after finishing P14.
“Then I saw that he launched and I tried to play fair. I opened the steering and tried to leave him some space and let us both live. He spun on his own axis and that kissed my car.
“I didn’t hit the wall but it sliced my rear tyre open and that’s where it all went too wrong. He was just too ambitious.
“My race engineer told me that he had passed Grosjean the lap before, and I could sense his move coming. But you have to weigh up your chances as a driver and know when it’s a real opportunity or not.
"I think he was impatient today, frustrated from yesterday and he wanted to get through the field. That’s Monaco, it doesn’t work like that.”
Leclerc however said the start of his race was 'fun', but agreed it ended in 'disaster'.
“It was very difficult. As I said before the race, I had to take a lot of risks, which we did,” he explained.
"It was fun at the beginning but unfortunately it ended in disaster. But that’s the problem with Monaco when you are starting 15th, which is not our real pace position. It was difficult to come back from today.”
