Xherdan Shaqiri scored an exquisite overhead kick on his Liverpool debut as his side thrashed Manchester United 4-1 at the Michigan Stadium.
Jurgen Klopp's team took the lead on 26 minutes when Sadio Mane stroked home from the penalty spot after Mohamed Salah was brought down by Demetri Mitchell.
But their lead did not last long as United levelled through Andreas Pereira's superb free-kick from 25 yards.
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 from Stoke City earlier this summer, then added gloss to Liverpool's win by firing home Ben Woodburn's cross in acrobatic fashion.
