Former Manchester United captain Gary Neville slammed Bruno Fernandes' behaviour during their 7-0 humiliation at Liverpool.
Fernandes again wore the captain's armband on the day.
Neville said, "I have to say what a shambles.
"Some of Fernandes' behaviour in the second half has been a disgrace. He is holding his hands up asking why am I not coming off?
"Ten Hag has dealt with setbacks in the past but this is a big one. They have fallen to pieces, lost their heads, their shape and their discipline.
"I never had them down as title holders.
"They have built up real trust but this is out of character. Hopefully, it is a one-off.
"This is a sore one. You don't lose 7-0 as a Manchester United player.
"That first 40 mins was a classic away performance. The second half has been an absolute disgrace, a shambles, epitomised by captain Bruno Fernandes who has been embarrassing at times.
"It's not their usual spirit and Ten Hag will deal with it very quickly."
