Former Liverpool hero Jamie Carragher says Manchester United's poor form means David Moyes' future at the club should be re-considered.
The former England international told SkySports ahead of the Red Devils' Champions League clash with Olympiakos:
"Liverpool have come here and won before, but not like that. I was watching it in shock.
"It was so un-Manchester United-like. The pressure is on the manager.
"It's getting to the stage now, where there are poor results, and poor performances. They have got to be looking at the manager's job."
Carragher's criticism was backed by another former Liverpool captain, Jamie Redknapp, who stated:
"I've never seen a Manchester United team so passive. They didn't lay a glove on Liverpool."
United go into their Champions League clash with Olympiakos needing to overturn a 2-0 deficit from the first leg.
