Manchester United interim manager Ralf Rangnick described his side's heavy Premier League defeat by Liverpool at Anfield as "humiliating".
United, who missed the chance to move level with fourth-placed Tottenham in the race for a Champions League place, dropped to sixth.
"It's embarrassing, it's disappointing, maybe even humiliating," Rangnick said.
Asked how United can close the gap to Liverpool, he added: "We have to accept they are six years ahead of us now.
"When Jurgen Klopp came they changed at the club and lifted not just the team but the club and city to a new level.
