A great touch, great movement and great finishing are not attributes for a complete/creative forward though, they're pretty vital attributes to aid a great goalscorer or pure striker as you put it.
When all is said and done, there's a reason why Lukaku's goalscoring rate isn't much better than Giroud's over the last 3 seasons and is nowhere near even Kane. There's a reason why he's very streky and has long periods where he looks like a donky. It's because he's lacking in many areas, even for a goalscorer.
