Yesterday’s Manchester United defeat was their joint-heaviest in a competitive game while it was Liverpool’s biggest win against their rivals.
At half time, Manchester were 1-0 down, and on the second half they allowed in Six goal.
“Second half it was not us. It was not our standards. We didn’t play as a team,” said Ten Hag, Manchester United coach.
“Yes, definitely, and surprised because I have seen the last weeks and months a team that is resilient and determined with a winning attitude. He replied to a concern whether he was angry of their second half experience.
“We didn’t stick to the plan, we lose our heads. We didn’t do our jobs. We didn’t track back and it was really unprofessional.” He added.
The 7-0 crush was United’s first defeat since they were thrashed by Wolves in December 1931, while the Red Devils were also beaten by the same score by Aston Villa in 1930 and Blackburn Rovers in 1926.
Ten Hag took over at United last summer and also suffered a 4-0 defeat by Brentford and a 6-3 reverse at Manchester City early in his tenure.
“We have seen in the past we can bounce back. After Brentford, after Manchester City. This is definitely a strong setback and is unacceptable,” said the Dutch National, Ten Hag.
“We let the fans down and I’m really disappointed and angry about it.
“It is a reality check… It’s a strong message [that] we get.” He complained.
The defeat at Liverpool came a week after Ten Hag won his first trophy with United when they beat Newcastle United to win the Carabao Cup.
“It was a really bad performance and the worst of the year,” said Ten Hag.
“We lost the game at the end of the first half and at the start of the second but you have to keep your head up and we didn’t.
“It’s all about showing discipline and we didn’t, so that’s when you start conceding goals.
“It’s a really unprofessional performance and unnecessary. You have to do your jobs and we didn’t,” Hag agonised.
“That was tough and we really have to thank them. I can’t blame them for leaving because it was a really bad performance, I’m ashamed myself for the fans today.” Ten hag said, referring to the fans who had travelled to Anfield.
Man Unitedare now third in the Premier League, 14 points behind leaders Arsenal and nine adrift of Manchester City after both won on Saturday.
