Moyes insists his side are capable of doing that and has asked for more of the same support from the fans as United go out "all guns blazing" at Old Trafford.
The manager told reporters: "The players are capable of turning it around. We're all desperate to put things right and make sure we play better to give the supporters here something to shout about.
"They shouted [against Liverpool] and we didn't give them anything on the field. When we went to Greece, the Olympicos fans played their part, so hopefully our fans will roar us on.
"We have to go for the throat to get the win. We won't be gung-ho but we will certainly go with a mindset to overhaul the deficit as quickly as we can.
"We won't be reckless as we could find ourselves with a bigger mountain to climb but we can be forceful. We have to be if we're to keep ourselves in the Champions League."
