Wednesday’s result against Olympiakos was exactly what the Red Devils needed.
Not just because the 3-0 win put them into the Champions League last eight but for their morale.
Moyes had an uncharacteristic spring in his step as he headed for the dressing room at half-time to issue what was likely the most spirited team talk of his short and tumultuous time at Old Trafford.
Minutes on from that moment, under-fire Robin van Persie completed his hat-trick, Old Trafford exploded with joy, and at least for a brief period, tranquility took over again.
After a night to sleep on it, however, questions surrounding United’s direction have re-emerged.
Lee Sharpe is once that remains unconvinced, harkening back to the moment that Moyes was confirmed as Sir Alex Ferguson’s successor.
This, interestingly enough, in that he sees the Scot as too much a reflection of his former boss in Manchester.
“I was a bit concerned when Moyes first got appointed,” he told talkSPORT. “I fancied someone a bit more creative."
“Someone who would bring something a little bit different to the club, like Arsene Wenger at Arsenal or Brendan Rodgers at Liverpool."
“Moyes is very similar to Fergie.”
Perhaps the comparison comes as a bit of a shock because of the differences between Moyes' first term and Fergie's last.
Yet of course, Ferguson himself struggled in his formative days at Old Trafford in an historical parallel to his heir’s experience.
Sharpe isn’t sold on the idea of Moyes being granted the same level of patience that the man who preceded him was.
Quizzed on the topic, the 42-year-old was hesitant to say that the ex-Everton boss will stay on the bench - even critical of the manager’s transfer dealings.
“I’m not sure,” he said of Moyes’ prospects for the 2014-15 campaign.
“If they’ve got £100m to spend on transfers, I’m not sure you are going to give it to him to spend."
“They are going to have to buy a whole new back four, because there’s a few of them going, and a couple of midfielders."
It's going to be a very busy summer for the Manchester United boss and this seems like another opinion he'll have to prove wrong regardless of the positive result last night.
