Match Summary
Manchester United's poor run of form continued at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more disappointment against Leeds.
Dominic Calvert-Lewin directed a first-period attempt against the woodwork for the confident hosts before Brenden Aaronson finished superbly with a driven, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had less time to prepare, the forward restored parity three minutes after the opener when he ran on to a through ball from introduced the Dutchman and slid a finish underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without several key attacking players due to a combination of fitness issues and international duty.
Not that you would expect the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post late on.
The draw prolongs Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, squandered.
With the AFCON reaching its knockout phase, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other attackers is having on Amorim's squad.
It's not that the missing pair are the answer to all of United's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, the boss has limited attacking options.
He evidently does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
After thrilling victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for the opener.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against their old foes.
However, there is a wider context for the manager and the club to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's position.
In contrast, he is now masterminding significant progress.
The task is not done yet but step by step, Leeds are getting closer to securing their survival.
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Turf Moor before also entering their FA Cup journey with a Old Trafford tie.
