Sir Alex Ferguson was seen shaking his head as his former club Manchester United fell to a 7-0 defeat at Anfield on Sunday.
Cody Gakpo, Darwin Nunez and Mohamed Salah each scored twice as Liverpool recorded their biggest ever win over their rivals, breaking a record which had stood for more than 125 years. Roberto Firmino rounded off the scoring late on during what will be his final season with Jurgen Klopp's team.
The result brought Erik ten Hag's squad down to earth, just seven days after a breakthrough Carabao Cup win under the Dutchman. It was also a heavier defeat than Ferguson ever suffered with the club, with the legendary manager's low point coming in the form of a 6-1 loss at home to Manchester City in 2011.
