Amorim becomes the sixth Portuguese boss to earn the award, following in the footsteps of ex-Red Jose Mourinho, Andre Villas-Boas, Nuno Espirito Santo, Bruno Lage and Vitor Pereira.
The last time a Reds manager came out on top was Erik ten Hag in November 2023.
Sir Alex Ferguson is way clear when it comes to individual wins, securing 21 trophies, with Arsene Wenger next best on 15.
Congratulations to Ruben from the entire staff at Manchester United!
