It's also completely unfair to Haaland to say "useless as they come aside from tapping in easy goals." Calling all Haaland's finishes "easy" is like saying "well, all Ovie does is pump them from the same spot on the PP, so it's not that impressive." The best scorers make it look easy, both of them do that.
That said... Haaland may be even more specialized than Ovie in the early years (not so now, where Ovie really has become pretty one-trick). Maybe, as someone else said, Ibrahimovic is Ovie, and Haaland is Hull... or something.
