Managers Jurgen Klopp and Jose Mourinho have clashed in recent days over spending, and it was Klopp’s Reds who came out on top in Michigan with goals from Sadio Mane, Daniel Sturridge, Sheyi Ojo and Xherdan Shaqiri on debut.
Andreas Pereira scored a free-kick for United but could not stop Liverpool making it two wins from three in the tournament and completing a Manchester double after their 2-1 win over Premier League champions City on Thursday.
Mane had scored a stoppage-time penalty to give Liverpool victory in New Jersey, and he was at it again in Michigan after a frantic opening 27 minutes.
United had seen a goal disallowed for offside when Juan Mata converted Alexis Sanchez’s pass, but it was Mane who opened the scoring from the spot after Demetri Mitchell felled Mohamed Salah.
United were level just three minutes later thanks to a stunning effort from Pereira, who curled home a free-kick from 25 yards.
The teams went in level at the break and while the tempo dropped in the second half, Liverpool continued to look the more threatening following the introduction of Shaqiri.
It was the Swiss who set up their second, bursting into the box and finding Sturridge who curled a first-time effort into the bottom corner after 65 minutes.
The Reds led 3-1 eight minutes later when Ojo netted from the spot after Ander Herrera caught Andrew Robertson, but the best was yet to come.
With nine minutes remaining, Ben Woodburn found Shaqiri in the box and the former Stoke man scored a stunning overhead kick from 12 yards to complete a comprehensive victory.
Having already faced two defeats in their first games against Borussia Dortmund and Liverpool, City dominated the opening moments but failed to capitalise on their chances as the German champions’ Meritan Shabani opened the scoring after 12 minutes.
Ten minutes later and Arjen Robben doubled Bayern’s lead after converting Franck Ribery’s pass, and things looked to be getting worse for the Premier League champions when new signing Riyad Mahrez was taken off injured in the first half.
His replacement Bernardo Silva narrowed the deficit just before the break, however, and 19-year-old Lukas Nmecha got City back into the game, equalising five minutes into the second half.
City continued to apply the pressure in the second half and Pep Guardiola’s decision to name six teenagers for the Miami squad paid off as 17-year-old substitute Adrian Bernabe played a part in Silva’s 70th-minute winner.
Speaking after the match, Guardiola said he did not know about the condition of Mahrez, who completed a five-year, £60million deal from Leicester City earlier this month.
But the Spaniard spoke highly of his young squad’s performance against his former club.
“We analysed our mistakes from the previous games and we played a lot better today. We started really well and had a lot of chances. We kept going and I am satisfied,” he told the club’s official website.
“We came here with a lot of young players and new players. So for them, it will be good for the future. It helps them to understand the game. I like to see my players fight for our teammates and play like a humble team.
“You cannot imagine how much I have enjoyed these two weeks with these guys. The young guys have desire. They open their eyes and listen because they have their whole career ahead of them. I want to say thank you to them.”

New Arsenal manager Unai Emery recruited Bernd Leno from Bayer Leverkusen earlier this summer, increasing the competition to be Emery’s first choice between the goalposts.
But Cech, widely regarded as one of the Premier League‘s best-ever goalkeepers, says Leno’s arrival does not mean he is set to depart the club.
“I want to fight for my place in this team,” Cech said.
