Manchester United gave new manager Erik ten Hag a perfect start with a dominating 4-0 rout of a lackluster Liverpool in Thailand on Tuesday.
Liverpool looked jaded and on the back foot for much of the match against a United side with superior fitness who capitalised on a slew of first-half errors in Bangkok with three goals in the space of 21 thrilling minutes.
The result is unlikely to trouble Liverpool manager Juergen Klopp. The German picked an experimental side, while United were nearly at full strength and Klopp played three separate outfield teams for half an hour each with the first two including a number of youngsters.
Yet United still outclassed its biggest rivals with Jadon Sancho, Fred, Anthony Martial and Facundo Pellistri all on the scoresheet and delighting Ten Hag, who praised his side's spirit in his first match in charge.
"I know we have good players, now we have to construct a team," he said.
"We have to not overestimate this result, we have to be careful. But still I've seen some really good things ... we have a lot of creativity and speed up front, we have the potential."
The encounter had a preseason feel with Liverpool using more than 30 players and United over 20.
Liverpool had the best of the early action and drew roars from the crowd of 50,000 before United went ahead after 12 minutes, when a Bruno Fernandez cross was poorly handled by the Liverpool defence, allowing Sancho to fire into the bottom corner.
Liverpool came close to equalizing soon after when new signing Fabio Carvalho's shot beat goalkeeper David de Gea and cannoned off the far post, with Luis Diaz hitting the upright in the ensuing scramble.
But the fightback was brief, with Liverpool's shaky back line exposed on the half-hour mark when Fernandez and Martial combined to lay the ball off to Fred, whose deft finish sailed over outstretched keeper Alisson Becker into the net.
United made it three moments later when Martial robbed Rhys Williams and coolly lifted the ball over Alisson, while Diogo Dalot almost added a fourth when his shot rattled the post.
United made 10 changes at halftime, after which Liverpool emerged better organised, with chances from its 75 million euros ($75.42 million) striker Darwin Nunez and Mohamed Salah, who was frustrated late on by De Gea and the woodwork.
United fended off a late Liverpool rally and completed the demolition with 14 minutes left, Pellistri latching onto an Eric Bailly pass on the counter and converting with ease after a one-two with Amad Diallo.
"The goals we gave away for United we really should get an assist for it to be honest," Klopp said.
"But I saw a lot of good stuff from our guys as well."
