The thing is the kid has been rated highly as a talent since very young, and predicted a future star. When he goes and display the sort of form he has for Dortmund at that age it is a huge sign he'll reach his heights. Of course he might not end up becoming a star just because it was predicted many years ago, but it means it is a lot more stupid to disregard him than older 'one season prospects'. He is similar to Martial in that regard, and about as a sure thing you can expect to find at this point. I haven't watched him that much even, but I wouldn't bet against him making it at this point.
