Same.
A lot of stems from the fact that they have a similar build and because Lukaku is a Drogba fan.
Didier's football IQ is superior to anything I've seen in Lukaku so far. And his skillset made him a perfect target man. A lot of tricks, flicks, pirouettes, and ability to cross from either wing,..you can go on and on.
Lukaku on the other, has more raw pace (not that Drogba was a slouch). A lot of his game revolves around his pace and power, and of course he is a fox in the box. Lethal with both feet.
