There may be plenty to talk about when it comes to United's recent failures to play as a team, supply decent chances to Robin van Persie and generally attack and defend as a unit, but the introduction of Adnan Januzaj into the first team by Moyes is a move that must be celebrated.
Watching a young star blossom in the club's colours is always a privileged delight for United fans, continuing on as it does from the ideal of the Busby Babes, Sir Matt's legacy and Sir Alex's vision.
That Januzaj not only impressed in his very first Premier League start against Sunderland but proved to be the game's decisive match-winner in was even more special.
Having felt his way into the time through a number of appearances from the bench, including an ill-fated half-time substitution for Shinji Kagawa against West Bromwich Albion, the youngster not only proved his quality but also his mettle by scoring both goals in United's 2-1 win.
The timing of his strikes, the first of which came on the 55th-minute mark after a difficult first half that featured a number of important saves by de Gea, suggests the 18-year-old has the mental strength and talent to become an exceptional player.
Moyes has much to do before his United team match the expectations placed upon them, but Januzaj's impact will be a boon to his authority as a decision-maker and hopefully an inspirational boost to the established squad members who have struggled to assert themselves on the season.
With the promise (and product) of youth lightening the mood around Old Trafford, the new manager can now break through the prevailing narrative of the past few weeks to put United on a more positive footing.
After all, Janzuaj isn't the only gamble Moyes has taken of late. His comments in the press questioning the calibre of United's squad and the level of contribution from his players was met with shock by pundits and fans alike. During Sir Alex's reign, the club was run practically under omerta as far as the media and public criticism of the team were concerned.
Yet his successor now has the perfect example to back up his claims and measure the efforts of players who aren't performing to the level required when representing United on the field.
Walking back into his dressing room of veteran internationals and serial trophy winners, Moyes can ask them all: If young Adnan can do it, why can't you?
