Charles Leclerc would probably have finished third had Ferrari decided to use a two-stop strategy 

Charles Leclerc pulled off an extraordinary home win for Ferrari at the Italian Grand Prix, ahead of the McLarens of Oscar Piastri and Lando Norris.
Ferrari chose a daring one-stop strategy for Leclerc, improvising mid-race, to vault him in front of the McLarens - who chose the conventional two-stop approach.
That left Leclerc hanging on in the closing laps from the rapidly closing McLarens and he just managed to resist them, winning by 2.6 seconds to send the tifosi in the grandstands wild.
Red Bull's Max Verstappen could finish only sixth, and Norris cut his championship lead by eight points to 62 with eight races to go, thanks to Norris grabbing the fastest lap before the chequered flag. McLaren are now just eight points behind Red Bull in the constructors' championship.
