I mentioned Rio back at HG 'cos he's playing the same kind of fringe role in the first team as Elliott did last season - he wasn't in HG's list 'cos he's come from the Ressies as opposed to being bought. Harvey got less than 800 mins all year, mostly when the league was done. Rio's on track for about the same now that Arne seems to have remembered that he exists.
If HG is going to include Elliott as a full member of last season's squad with those minutes, then including Rio in this season's is also fair.
As for Morton (who you're trying to shoehorn into an argument, despite forgetting how to spell his name )
Our young player depth is definitely a bit s***e at the moment, but (unfortunately IMO) it doesn't really matter 'cos players like that didn't - and will seemingly never - get game time here under Slot in the same way that they did with Jurgen.
