Wouldn't trust any of them as fully qualified first team squad players yet, but imo most of them should be getting game time next season if they are to stay here. Otherwise they need to be out on loan.
But if they could stay together at City as a group, continue to develop together & also get the occasional chance in the first team, then we could create something really special imo. I think you would find one or two start to look useful at first team level, & by the end of next season we would be really talking about promoting a bunch of them for the season after. They play very well together. That shouldn't be thrown away.
