Almost a month now since Puig saw any minute, it would be a bit rough to put him into the starting line up immediately and expect a good performance.
Maybe Koeman will do that in order to create a win-win for himself, I cannot even write that without blushing, but I think it has very much looked like the cow has done things like that before.
Or maybe he chooses Demir instead, who has sat for even longer after Koeman went from loving him to hating him. All these younger (and older) players should be given more chances in better circumstances and then rest sometimes and play for Barcelona B too, not be either completely trusted or mistrusted prematurely.
