Mejbri crashed out against Jordan Henderson and Naby Keita after being introduced in the 84th minute of Tuesday’s Premier League clash at Anfield.
He replaced Anthony Elanga and made an instant impression, displaying energy and passion in the middle of the park.
The 19-year-old was booked for his challenge on Henderson and risked a second booking when he hit Keita moments later.
Gary Neville loved what he saw of the Tunisian international and was “proud” of his effort, with Man United fans praising his brief performance.
Hannibal Mejbri, a 19 year old, came in and showed more passion and desire in 5 minutes than the rest of the team combined in the entire 90 minutes.
I say bench these righteous, characterless individuals and play with the kids for the rest of the season. pic.twitter.com/yyfE2RDQzN

Hannibal Mejbri showed more pride and passion in five minutes last night than the rest of that Manchester United, he looked hungry, he showed desire and he fought for the shield. He was making tackles, for me on Saturday he would be a starter at Arsenal, nothing to lose and he wants it

“To be fair, at least the boy is showing a little something,” Neville said in the comments. “Honestly, it takes a little kid to show the rest how to run to the ball and put up a challenge.”
“In fact, I’m proud of him. Maybe he doesn’t like the idea of Liverpool players walking around him. I wish the rest of them were the same.”
Mejbri was making only his second appearance for Man United having made his league debut for the club against Wolves on the final day of last season.
Neville was able to take something positive out of a crushing defeat for his former club, with Liverpool winning 4–0.
Luis Díaz opened the scoring, with Mohamed Salah doubling Liverpool’s lead.
Sadio Mane and Salah scored their team’s third and fourth in the second half to move to the top of the league.
