Reactions from United fans online were as predictable as they were pained.
@boivannie fumed: "Hojlund scores on his debut? Wow we’re cursed 😭😂."
Another @bigger_uncle vented: "So United was the problem."
@Houdini__1 turned his frustrations towards new arrival Benjamin Sesko, signed from RB Leipzig for £74m: "Hojlund who didnt play most of preseason or start the season with us is already starting and scoring for Napoli but Amorim is taking 600 years to start Sesko."
@August19___ summed it up with brutal humour and said: "Hojlund already balling 😂😂😂😂😂😭Manchester United might be truly cursed ."
@anugbomi added: "So Hojlund remembers how to score in back to back games."
