Indeed. And it's why Lukaku is in a farmer's league having won nothing in his career, instead of Barcelona/Real Madrid despite being an astonishingly good goalscorer, quite possibly the best in world football.
You can have a goalscorer score two goals a game every round of a cup tournament, yet if he doesn't turn up in the final or any given round, you're playing that game with 10 men.
It's a different approach to understanding football - loads still have the "Roy Of The Rovers" mentality, where if a striker scores he's "done his job". That hasn't been the case for nearly a decade now but that archaic mindset still persists.
I'd rather have a striker score 15 a season and be the DCL type of player, than score 25 a season and be a Lukaku type. Because the cohesion and consistency of the team, game after game, is much better - there's a glass ceiling on what you can do with just a goalscorer up front.
