DCL and Lookman both have good technique, but they both get quite easily isolated and don't have a particularly big footprint on games. They are more quick and tidy but also predictable, they don't take many risks or create much that isn't on offer. They'll find a yard to get a shot or pass away, but they are popping out the box rather than tearing it apart.
Someone like Bolasie who wants the ball and commits defenders is frustrating, but it doesn't need to work as often to produce better results. Onyekuru has scored 14 in 30 games, and is currently joint top scorer in Belgium with 5, so output looks pretty decent on paper at least.
Has Thierry Henry as a role model and you can see a few similarities in style and play, obviously no where near the touch or final ball of Henry when he was good.
