It's the first prize that the Morocco international has claimed at United, since his summer move from Bayern Munich.
He saw off stiff competition from Amad and Andre Onana, at the end of a month where the Reds were unbeaten in all competitions, after three games under the temporary stewardship of Ruud van Nistelrooy and a pair of fixtures with new head coach Ruben Amorim in charge.
Nous was named in the starting XI for all five games but actually played in three different positions, showcasing his dependability and versatility.
After a Man-of-the-Match performance at left-back in the 1-1 draw with Chelsea, he occupied a more familiar right-back slot for the win over PAOK in the Europa League.
