Match Summary
Manchester United's poor recent struggles continued at Elland Road, but manager the Portuguese tactician had Matheus Cunha to thank for the team not suffering even more damage against their old rivals.
The Everton loanee directed a first-half effort against the post for the in-form hosts before the American midfielder finished superbly with a driven, 62nd-minute effort.
With the goal, the United boss was in the firing line after his side had failed to beat bottom-of-the-table Wolves at Old Trafford earlier in the week.
However, against opponents who had two days less to recover, the forward restored parity three minutes later when he latched onto a through ball from substitute the Dutchman and guided a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a combination of fitness issues and national team commitments.
Not that the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned his teammate'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 in the dying moments.
The point prolongs the home side's unbeaten run to seven games, their best such streak since 2001, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, squandered.
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other attackers is having on Amorim's squad.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the expensive frontman looks no better than previous struggling signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of expected atmosphere, but the hostile edge was not as evident as in previous fixtures.
The home fans were more concerned about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, 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 campaign, many thought about the manager's position.
Instead, he is now masterminding clear improvement.
The task is not done yet but step by step, the team are getting nearer to securing their survival.
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Turf Moor before also entering their FA Cup journey with a home tie.
