Don't really agree here. Conte is no mug, he'll be looking to keep all of his squad as sharp as possible, and he'll likely look at games as a "horses for courses" scenario. I think he'll also operate a meritocracy, so if Richarlison gets the opportunity, tears it up and gels well with whoever in the front line he plays with, then he'll stick with him until either he goes off the boil, or he sees another player as more suited to starting against a certain team.
The long and the short of it is that every player has to give Conte a selection headache, whilst simultaneously accepting that they're not a shoe in for a starting place regardless.
