Still, the visitors could not hold out and stayed behind Sheffield United, who lie sixth in a brilliant first season back in England’s top flight.
Man United were woeful in the first half, outplayed in every department and slipping behind to a goal from midfielder John Fleck in the 19th minute.
Lys Mousset then added a second goal for Sheffield United before the hosts started to tire and Man United began attacking with pace as they fought back.
Man United coach Ole Gunnar Solskjaer admitted his players had been outfought for 70 minutes but insisted their comeback showed a new sense of belief within his squad.
“The difference between this year’s team and last year’s team is huge,” he said.
“My head goes back to Everton last season [when United lost 4-0 at Goodison Park]. These boys never give in – last year we would have been three, four, five down.”
On his side’s slow start, Solskjaer added: “It’s not something you can put your finger on here and now but they looked like they wanted it more than us. We had one shot on target in the first half and it’s not acceptable.
“When you’re 2-0 down you’ve got to go for it, play with less fear and just express yourself.
“These boys have shown themselves what they’re capable of, but you have to learn from that disappointing first 60-70 minutes.”
