The Buddies were hosting United in tonight’s top of the table clash in the Scottish Championship, with the winner having the chance to put themselves in the driving seat for automatic promotion.
And while the first half was a physically-demanding and tough-tackling affair, the second 45 minutes have allowed Morgan to show his true attacking talent.
The winger is understood to be on the verge of completing a move to Celtic in the January window, with St Mirren boss Jack Ross desperate to sign Morgan back on loan until the end of the season.
And you can understand why Ross is keen to see the 21-year-old extend his stay, even if only temporarily, after watching his first goal tonight.
Prior to kick-off St Mirren held a two point lead over Csaba Laszlo’s side, a gap they have since extended to five with Morgan’s brace securing a 2-0 victory.
