Jamie Carragher echoed those sentiments on Monday Night Football, describing the display as the best he has seen from United under Amorim. The opening half-hour, in particular, reminded him of the Sir Alex Ferguson years, defined by ambition and relentless pressure.
"It's the best I've seen Manchester United play, certainly in the first half, under Amorim, maybe going back to the first game of the season with Arsenal," the former Liverpool defender said.
"Manchester United were fantastic in those first 25 to 30 minutes. It was almost a throwback to Sir Alex Ferguson - fast, attacking football, people being energetic, making runs forward, being positive being on the front foot, winning the ball back early. There as lots of that. But clean sheets are a big problem for them. They had problems at both ends of the pitch last season. We highlighted pre-match that they're improving in attack and we saw that again tonight. I thought the attacking players for Manchester United were fantastic."
Yet the praise came with a familiar caveat. Defensive fragility remains a glaring issue. United have now managed just one clean sheet in 15 league matches this season, with only bottom-placed Wolves faring worse.
"They had a lot of young defenders out there tonight that didn't help," he said. "I've been there, more often than not when you make a mistake as a young defender, it ends up in the back of your goal and that was the mistake tonight. Even though it ended up at 4-4 and Bournemouth should have won it at the end, Manchester United were by far the better team.
"That was the first time in a long time, and certainly under Amorim, that I felt like I was watching how Manchester United should be. Just wave after wave of attacks, counter-attacks, and almost the opposition feel like they're getting sucked back into that box in front of the Stretford End. You can't get out."
