Leclerc's performance the last laps laps was dismal. He completely lost his head, heavily overdrove his car and tires in corners and under braking and losing it entirely a couple of times.
I think he’s a bit frustrated. Ferrari have kept going backwards in his time there, and it’s got to hurt to see Max, who he kept up with almost 1:1 in all the junior formulas, winning everything and taking every record.
But yeah, his driving at the end was abysmal. The tifosi would have lost it if he took out Sainz in T1 of the final lap
