Amorim has the backing of United's board.
The dust is beginning to settle on Manchester United's defeat in the Europa League final.
United's season revolved around winning the Europa League for a few months and they stumbled to a 1-0 defeat at the Estadio de San Mames after a first-half goal from Brennan Johnson.
The defeat means there will be no Champions League football at Old Trafford for a successive season. United have endured their worst campaign for 51 years, and Ruben Amorim has promised to quit without receiving any compensation if the United hierarchy feel he is no longer good enough to be their coach.
However, Amorim is understood to still have the board's backing and he is set to remain in charge for next season, which means he must be supported in the summer transfer window.
There are supporters who have questioned whether Amorim is the right coach to take the club forward, though, especially ahead of what will be a crucial transfer window.
United cannot afford any mistakes in the transfer market this summer, but would persisting with Amorim be a mistake? Here are the arguments for and against sacking Amorim:
Against: Amorim inherited the squad
Can Amorim be judged fairly when he inherited a squad that was assembled by his predecessors? Erik ten Hag spent over £400million during his tenure and left behind practically nothing to show for it.
United spent £108.5m on two strikers who struggle to score goals. Amorim has gone from working with Viktor Gyökeres, one of the most prolific goalscorers in Europe, to coaching Rasmus Hojlund and Joshua Zirkzee, who have scored just 17 goals between them in all competitions this term.
For comparison, Gyökeres has netted 53 goals for Sporting Lisbon this season and Amorim was dealt an impossible task when he agreed to take over a side with no natural goalscorer.
The dressing room needs to be gutted. The majority of the players are not good enough to represent the club following an utterly joyless campaign.
Of course, he needs to improve the players he inherited - that is part of his remit - but you can't make a concrete judgement on Amorim when he inherited a mess of a squad.

For: the Premier League campaign
There is no getting away from the disastrous Premier League campaign. United have been shocking and they will record their lowest points total in the Premier League era.
Wherever you look, the league statistics make for grim reading. Amorim has won just 24 points in 26 games, averaging a 0.92 points per game. United last beat a team that wasn't relegated on January 26.
Amorim's points ratio is even lower than Paul Jewell's 0.94-per-game average during Derby County's infamous 2007/08 campaign, when the Rams set the top-flight's lowest ever points total.
Since Amorim's appointment in November, United have been beaten by Nottingham Forest, Bournemouth, Newcastle, Brighton, Crystal Palace, Wolves and West Ham at Old Trafford.
United have lost a record 18 games in the league and have a goal difference of -12.
The team's focus shifted to the Europa League in February, but the lifeless performances in the league haven't been acceptable and Amorim must hit the ground running next season.
Against: an impressive communicator
Amorim has shown himself to be an impressive communicator in press conferences and interviews, which has helped his reputation among fans, who haven't turned against him.
"We'll back him from the Stretford End," has continued to be chanted to the tune of Bonnie Tyler's hit It's a Heartache despite the awful results, and the way Amorim has communicated has helped his cause.
Amorim is convinced he knows what needs to be done to turn the club around and he is articulate when he speaks to journalists. More importantly, the players seem convinced in his plan, as Bruno Fernandes, Luke Shaw and Diogo Dalot all backed him after the Europa League final.
Speaking in the mixed zone, Shaw said: "I think there's a lot of things that need to be changed. I think that's why Ruben is 100% the right person.
"He knows and he can see day in and day out at the club, not just on the pitch but off the pitch, around the club. The standards, the mindset, like I said, I think he sees everything. I think he knows what he needs to change."
Shaw will not decide Amorim's future, but those quotes were strongly in favour of the 40-year-old.
Amorim has insisted he knows what needs to be done.
For: formation concerns
United are at a crossroads after failing to qualify for the Champions League again. The financial picture at Old Trafford is pretty bleak and the kitty is close to running dry, if you believe Sir Jim Ratcliffe.
That's why this summer is so important. It could be a make-or-break window that decides the club's trajectory for the next five years and United must be sure they have the right coach.
So is Amorim's formation the final 'game model' for Ineos' decision-makers? They must decide whether 3-4-2-1 will be the team's set-up over the next few years because that would ease concerns about backing a manager this summer who insists on playing said system.
It would be a disaster to back Amorim and sign players for his formation this summer, only to sack him a few months into the season and appoint a manager who plays a different system.
The academy teams currently don't play in Amorim's formation and United need to decide on their preferred style. Is this how they want United to play?
Crystal Palace won the FA Cup and Inter Milan are in the Champions League final. They both play with a back-three and show the system can be successful with the right players.
But there are concerns about whether United are settled on the formation and it would be a spectacular mistake to buy players who are tailor-made for Amorim and then to sack him.
There are doubts about Amorim's formation.
For: Europa League final defeat
Considering United gambled everything on the Europa League final in Bilbao, a better performance was expected. United were awful against Tottenham and produced a shameful display.
United struggled to lay a glove on one of the worst Tottenham sides in recent history, and they looked like the club that hadn't won a trophy since 2008. To lose a European final, against a club who are notorious for losing their bottle when it matters, in that manner was appalling and Amorim got a lot of decisions wrong.
The starting XI was wrong, Amorim's tactics were wrong and his hesitation to make substitutions in the second half when the game was getting away from United didn't make sense.
United did not go down fighting and never looked like equalising in the final minutes of the contest.
Amorim's in-game management was lauded when he arrived from Sporting, but he failed to recognise his team selection was wrong and waited too long to introduce fresh legs.
United were awful in the final.
Against: lack of alternatives
Earlier in the season, the thought process with Ten Hag was that he shouldn't be kept solely because there was a lack of alternatives. There was enough evidence to suggest Ten Hag needed to be sacked regardless, but Amorim's situation has not reached that stage.
There is not an overwhelming body of evidence to overlook the lack of alternatives - the likes of Jose Mourinho, Kieran McKenna, Gareth Southgate, Xavi, Thomas Frank and Marco Silva - and sack Amorim.
Could another coach have done a better job than Amorim this season? Probably, but that doesn't necessarily mean a change should be made this summer after just seven months.
Against: trust in the academy
Having a connection with the academy and trusting young players hardly matters when you're 16th in the Premier League, but Amorim does appear to understand the club's tradition.
Although the promotion of some academy players to the first team has been enforced due to injuries, it has been encouraging to see Amorim give prospects the chance to be involved.
It is obviously better to have a coach who is keen to give United's youngsters a chance.
