Patino, Hutchinson and Norton-Cuffy are the ones I think will have a lasting impact on the first team, but it's really just a guessing game at this stage. Injuries and opportunities will shape their careers just as much as talent in the end. Catalin Cirjan had a similar impact to Marcelo Flores in his first season for instance, but then he lost form and got a bad injury which he's still recovering from, and now no one includes him on these lists anymore.
I'm surprised that Mika Biereth isn't included in the main post, by the way. The odds are maybe stacked against him with him being a striker and all, but he's undeniably better than half the lads on the list. Just a clever and dead useful player, good at almost everything and seems to have the needed mentality to stick with it when the going gets tough.
