Leclerc has already lost his chance for the championship if we look at this from a sensible aspect. He is still trying to be competitive of course but the car isn't letting him do better than this. At least there was some improvement in the Monza Grand Prix as he was faster than Russell and Hamilton both. But nothing has changed against Verstappen. It was really awkward to see Leclerc having a serious problem despite having fresh soft tyres after that important pit. If Verstappen is able to keep the gap at the same level with worse tyres then Ferrari are finished for this season.
Yeah RBR is in a much better state now, nobody seems able to compete with them, and when they can, Fia changes the rules.
The championship is over, better to stop the upgrades and save money for the next year
