Yeah, or Bruno (@devilish showed how their heatmaps overlap a lot), or Jesus apparently. But then that's his role at Bologna, @devilish also pointed out that he had been a fairly prolific striker at Anderlecht, when he was put in goalscoring role.Is he sort of like Firmino?
So I don't know what's intended here, but he might be seen as a back-up/successor to Bruno rather than Højlund - or the City game plan (Bruno as a false 9) might be intended to be used more. Either way, United most likely aren't seeing Zirkzee as someone who can replicate Højlund's role when the latter's unavailable.
