The Red Devils will fly to Ukraine later today for a Champions League encounter with Shakhtar Donetsk that has taken on additional significance following Saturday's Premier League defeat by West Brom.
The loss was the club's third in six games this season.
It represents their worst start to a league campaign since 1989 and has seen them slide into the bottom half of the table and pushed out to fourth favourites to retain their crown, with the bookmakers believing United will be battling Tottenham for the final Champions League place.
Yet, despite the intense glare of scrutiny on United from the outside, inside the club there is a sense of calm.
It is understood that work is continuing to identify suitable targets and the Glazer family, having handed Moyes a six-year contract as Sir Alex Ferguson's successor, are determined to provide the Scot with the required financial muscle to strengthen his squad as he sees fit.
Yet fans hoping for an influx of players in January may be disappointed.
Although United have made significant signings during the mid-season window, Patrice Evra and Nemanja Vidic being the most obvious examples in 2006, it is a notoriously difficult time to do business.
Many top players are cup-tied from European competition and even though two of the most obvious options - Leighton Baines and Ander Herrera - do not fall into that category, Everton and Athletic Bilbao may view them as essential in reaching targets that have been set for their respective clubs.
Red Bull Salzburg defender Martin Hinteregger, who is capable of operating both at left-back and in central defence, is apparently also on United's radar.
"I confirm there is interest in me from Manchester United and a top Italian club," the 21-year-old told talkSPORT.
"I am honoured, I honestly did not expect that. Actually my goal is to stay here, but in any case I will talk to my agent and consider whether a transfer might be beneficial."
There is an acknowledgement at United that a difficult adjustment was not helped by the decision not to buy Moyes out of the final six weeks of his contract at Everton once it had been confirmed he would replace Ferguson.
The decision cost Moyes the chance to get to know some members of staff, including the scouting network, which meant he was effectively starting from scratch when he officially took charge on July 1.
Not that Moyes is completely blameless for the present situation.
After all, the Scot is solely responsible for £15million new boy Wilfried Zaha being left on the sidelines since impressing in the Community Shield.
Zaha was on the scoresheet along with fellow youngster Adnan Januzaj during Monday night's Manchester Senior Cup win over Bolton, although it remains to be seen whether Moyes will even select the pair in his squad for the Donetsk trip.
