The boy, called Charlie, was asked his opinions by the United YouTube channel, Full Time Devils, after full-back Chris Smalling was sent off, putting his team on the back foot.
Charlie admitted to his frustrations and called Smalling 'a bit of an idiot' after his stupid sending off, and added his disappointment with the showings of wingers Adnan Januzaj and Angel Di Maria.
He also voiced his pleasure at seeing United skipper Wayne Rooney return.
Shearer, Lawrenson, Savage...there's another kid in town!
Story continues after video...
Charlie's mature performance has echoes of five-year-old Noah Ritter, who became an internet sensation after repeatedly using the word 'apparently' during a TV interview.
Noah, from Pottstown, Pennsylvania, became an overnight star earlier this year after giving a hilarious interview with a TV station at the Wayne County Fair in August.
In the video, a newscaster was seen approaching him on the opening day of the fair in Honesdale and asking him what he thought of a new ride.
Noah said into the microphone: "It was great and apparently I've never been on live television but apparently sometimes I don't watch the news because I'm a kid and apparently every time Grandpa just gives me the remote I have to watch the Powerball."
The news reporter pushed him further, asking him again for his view on the ride.
Noah replied: "Well, it was great because apparently you're spinning around and apparently every time you get dizzy, that's all you do is get dizzy.
"I've never ever been on live television."
Noah used the word 'apparently' no less than eight times during the one-and-a-half-minute interview, and repeated that he had never been on live television three times.
