The race started and immediately was very wet, Leclerc decided to put and sent his call in for tyres seemingly once he was in the pit lane already. The team therefore didn't have tyres ready for him. He contests that in weather like that the tyres should be being prepared in case a driver needs to pit.
It seems likely that Ferrari processes will change to allow them to have more agile strategy going forwards.
I saw an analysis of this. Checo tends to stop exactly to the millimetre at the right spot so the mechanics don't need to manoeuvre any more. With Max it tends to be a centi this way or that way and that makes a difference when the mechanics need to readjust hand position and such.
But if there's a blunder or a strategy error, Checo is the one to get them.
It's not a conspiracy or anything. Just weird. Same thing was with Hamilton and Bottas.
