Xherdan Shaqiri scored an exquisite overhead kick as Liverpool thrashed Manchester United 4-1 in the International Champions Cup in front of 101,254 fans in Ann Arbor.
Jose Mourinho named a starting XI including five players who did not feature in the Premier League for United last season, while Liverpool fielded a strong side featuring Mohamed Salah and Sadio Mane.
Jurgen Klopp's team took the lead on 26 minutes when Mane stroked home from the penalty spot after Salah was brought down by Demetri Mitchell.
But their advantage did not last long as United levelled through Andreas Pereira's superb free-kick from 25 yards.
Liverpool substitute Daniel Sturridge continued his impressive pre-season form when he scored with his first touch after 66 minutes before Sheyi Ojo added his side's second spot-kick of the game six minutes later.
Shaqiri, who arrived for £13m from Stoke City earlier this summer, then added gloss to Liverpool's win by firing home Ben Woodburn's cross in acrobatic fashion.
Liverpool round off their pre-season preparations with a trip to Dublin to face Napoli on Saturday (18:00 BST), before hosting Torino at Anfield on 7 August (19:30 BST).
United continue their International Champions Cup (ICC) campaign against Real Madrid in Miami on Wednesday (01:05 BST), before facing Bayern Munich in a friendly at the Allianz Arena the following Sunday (19:15 BST).
Liverpool's attacking options shine through
Such is the excitement surrounding Liverpool's current crop of players, footage released by the ICC on Friday showed fans waiting up to eight hours to catch a glimpse of their heroes outside the team hotel.
Salah went close after nine minutes as he met Mane's through ball to direct a looping header goalwards, only to be denied by a leaping Lee Grant.
Showing no signs of the shoulder injury which forced him to be substituted early during the Champions League final and then struggle at the World Cup in Russia, the Egyptian was a menace throughout.
That menace came to fruition after 26 minutes when Demetri Mitchell fouled the forward in the penalty area to hand Mane the chance to score from the spot. He duly obliged.
After a sharp opening 45 minutes, Salah and Mane were replaced by Sturridge and Shaqiri, and it did not take long for them to show their own qualities.
They combined for Liverpool's second, with Shaqiri laying off for Sturridge to apply a trademark delicate finish.
And although Shaqiri arguably stole the show late on with his spectacular overhead effort, Liverpool's attacking depth shone through.
With Roberto Firmino - who scored 27 goals last season - still to return, Klopp's forward line looks a force to be reckoned with in 2018-19.
Sanchez left frustrated
Seconds before Liverpool took the lead, Matteo Darmian galloped away down the right flank with Alexis Sanchez and Juan Mata seemingly in acres of space in front of him, only for Alberto Moreno to cut out his attempted pass.
Sanchez's scream of anguish was audible over the near-capacity Michigan Stadium crowd.
It was a theme that continued throughout, and despite moments of brilliance with the ball at his feet, the Chilean's frustrations were too often on show for all to see.
Though several heavy challenges from Liverpool's centre-backs did little to help his mood, Sanchez's irritation threatened to boil over towards the end of the first half after he was penalised for handball.
Without the likes of Romelu Lukaku, Marcus Rashford, Jesse Lingard and Paul Pogba - who are taking breaks following their World Cup exploits - Sanchez may have felt United's attacking threat rested solely on his shoulders.
Sanchez summed up his game with 15 minutes left, as after brilliantly holding off two Liverpool defenders, he could only fire high and wide with just the goalkeeper to beat.
The Chilean was substituted shortly after as Mourinho opted to give some of his younger players a run-out, and again Sanchez did little to hide his frustration.
