Manchester United manager Erik ten Hag says his side “lost our heads” in the 7-0 thrashing by Liverpool on Sunday.
The defeat was United’s joint-heaviest in a competitive game while it was Liverpool’s biggest win against their rivals.
Ten Hag’s side were 1-0 down at the break before letting in six goals in the second half at Anfield.
“Second half it was not us. It was not our standards. We didn’t play as a team,” said Ten Hag.
Asked if he was angry with his side’s second-half display, he added:
“Yes, definitely, and surprised because I have seen the last weeks and months a team that is resilient and determined with a winning attitude.
“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.”
