I still think the Lukaku comp is spot on for Darwin. Very limited technically. Cant control a ball, cant pass a ball, and can barely run with the ball. HOWEVER just like Lukaku he is a physical specimen who has good positioning and scored lots of goals.
You can make fun of Lukaku all day but he has always scored goals consistently and I think that might apply to Darwin.
Now if you compare Darwin to the last 3 TOP Uruguyan strikers, Forlan, Suarez, and Cavani he is literally nowhere near or close to their ability IMO.
