When debutant Sean Longstaff was introduced at Anfield, warm applause could be heard from the away end - as United fans also chanted: "Sean Longstaff, he's one of our own."
A few minutes later, the travelling Toon Army were then signing, "If Longstaff scores, we're on the pitch", something the midfielder insists he did not hear at the time - with the 21-year-old instead learning of the chants after the match when his team-mates informed him of them.
Longstaff added: "I heard it briefly when I came on. It wasn't until I was in the changing room after that the lads were saying they were chanting: 'If Longstaff scores, we're on the pitch.'
"The lads were saying: 'Imagine if that chance had went in.' Obviously, it is what it is, and for them to be signing about me - I've been there singing about other players.
"It's an unbelievable day, ruined a little bit by the scoreline. In 10 or 20 years' time when it's all done, no-one's going to remember that we got beat 4-0. I'll remember making my debut. It's a great day."
