Martin Brundle has called for Charles Leclerc to "stop making so many mistakes" after a costly weekend at the Miami Grand Prix.
The Monegasque crashed out twice across the three days, first losing control of his car at Turns 7 and 8 during Friday practice before spinning into the barriers at the preceding corner in the final session of qualifying.
Leclerc struggled to make up for his error in the race, finishing only seventh, with Ferrari's lack of race-run performance and tyre degradation issues costing the team dearly again.
But mistakes have been a constant theme for Leclerc in his time at the team, from his qualifying crash in Baku in 2019 to the incident that saw him fail to start his home race in 2021 and the title-defining error in France last year.
"He is breaking an awful lot of Ferrari parts and costing opportunity," Brundle told Sky Sports F1.
"He is every bit as quick as anyone else, if not the fastest driver out there in terms of raw pace but he doesn't seem to know where the limit is.
"I remember saying when he was at Sauber, 'I cannot wait to see this lad in a Ferrari'. But he is going to have to stop making so many mistakes. It has been around a few years now and I think he drives absolutely to the ragged edge of the limit and it keeps catching him out.
"He has got to take a fraction out of that."
Viewed by others:
On whether Leclerc was guilty of over-driving, 2009 World Champion Jenson Button replied: "Yeah but he is also guilty of over-performing.
"It is a tricky one, he probably does take more risk than most and he has even said that in qualifying, but he has also put it on pole position when we didn't think they had a chance over the Red Bull, so it is a tricky one.
"We are always going to pick him up on what just happened. I like how he goes racing, I like how he puts everything on the line."
