Amorim replaced Erik ten Hag last November despite reportedly wanting to come in during the summer rather than mid-season.
After enduring a nightmare start to his tenure, United appear to have turned a corner, winning their previous three Premier League games.
Things could have been very different, however, as United had Thomas Tuchel and Roberto De Zerbi ahead of Amorim on their wishlist.
The Athletic’s Andy Mitten has since revealed why the two decided against joining United, saying in his recent column: "United leaned towards Tuchel and De Zerbi — the latter considered a bit of a maverick but ultimately a top coach.
“Tuchel came to Monaco for a meeting with United’s leaders two weeks after the FA Cup final, in which Ten Hag’s side outsmarted and defeated Manchester City for a momentous win.
“Tuchel came across incredibly well, but no terms were agreed and the German wasn’t ready for the United job. He was to take a short break from football after a difficult time at Bayern Munich that led to him leaving that club only the previous month.
"So De Zerbi became the frontrunner, and financial terms were discussed with the Italian in line with what United felt was fair.
“Those terms were rejected, and the club chose not to improve them. De Zerbi’s next job was instead at Marseille in France, where he’s unlikely to be on the same level of pay as a United head coach would be getting."
