There's nowhere to hide for the Scottish manager, who has received another battering in the press and is being lined up for the sack by many columnists after the Old Trafford rout.
Jamie Redknapp, Sky Sports pundit and writer for the Daily Mail, sums up a situation that must baffle Moyes himself:
After a result like that, David Moyes must be thinking, 'What is going to happen to me here.' The game against Olympiakos on Wednesday is massive. If they go out, that is United done with Champions League football for 18 months.
Many are pointing toward the Olympiakos fixture as make or break for Moyes. Should the Red Devils fail to overturn a 2-0 goal deficit against the newly crowned Greek champions, it's the common consensus that Moyes' head will be on the chopping block.
Mark Ogden of The Telegraph also pinpoints the upcoming Wednesday tie, saying "pessimism and fear" now take the place of "cocksure self-belief at Old Trafford," a factor highlighted against Brendan Rodgers' fearless Reds:
"A 3-0 victory against Olympiakos on Wednesday, which would put United into the Champions League quarter-finals, is perhaps the only result which can now save Moyes," writes Ogden.
Moyes' willingness to play Juan Mata—one of the world's best No. 10's—in a wing position has left many bemused. The Spaniard is yet to score for United and struggles to exert his influence over games. But for Robbie Savage of BBC Sport, this isn't the only tactical mistake the former Everton manager made:
I was at Old Trafford on Sunday and United were absolutely battered in every area, and on their own patch. United boss David Moyes did not deal with Liverpool in any department—defence, midfield or attack.
Alan Hansen, former Liverpool defender and columnist for The Telegraph, outlined Moyes' latest loss as his "lowest point since he was given the job." That's quite a statement considering the plethora of poor results United fans have witnessed since Moyes took over.
Moyes' embarrassment is perhaps amplified loudest on Twitter, where stats and quick-fire opinions capture the disappointment most succinctly. Squakwa offered insight into the dismal run United find themselves on:

Wayne Rooney acknowledged the defeat as one of his "worst" moments in football, as reported by the Mirror and via Nick Sutton of BBC Radio 4:
Paul Higham, senior reporter at Sky Sports, posted a banner held up by the Liverpool end during the tie. Its sarcasm highlights exactly how rival fans are feeling about Moyes' reign:

While Moyes has combated talk of the sack for some time, this latest mishap could have fatal repercussions on his Old Trafford tenure. It is difficult to see how he can continue if losses to Olympiakos and Manchester City follow, and that's without considering a difficult trip to West Ham.
Moyes' position certainly appears untenable to many outside the club. Unfortunately for fans who wish to see the back of him, the decision-makers are yet to show any kind of lethality, much like United's players on the pitch.
