When you loan out most of the players in or approaching the main age group for breakthroughs (20-22) that limits your options though. I also don't think the group not out on loan look ready yet, most seem very lightweight as we saw against Chelsea and when Pozo was given a few appearances. Maybe you could try Barker as a last 10 minute impact sub but against higher caliber opposition recently (Schalke, Chelsea) he has been handled quite easily. If Lopes, Denayer and possibly even Rekik (I'm not a big fan, though) were here, I think they'd be closer because they are now close to being men rather than boys. Denayer would certainly be on the bench ahead of Boyata. When this crop of 17-18 year olds are 20-22 and have some experience it will be very interesting to see how good they are because they look better than our previous youth generations.
