At a Glance
- Calvert-Lewin sees a first-half header come back off the upright.
- Aaronson puts the home side ahead with a well-placed finish in the second half.
- Matheus Cunha levels just three minutes later.
- Leeds continue their longest top-flight undefeated streak since the turn of the century.
Manchester United's poor recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-half effort against the post for the confident home team before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, the United boss was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had less time to recover, Cunha levelled three minutes later when he latched onto a pass from substitute Joshua Zirkzee and guided a shot underneath advancing Leeds 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 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.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impression, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the match, also blasted against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven games, their best such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's squad.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost instantly 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 showing, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and conviction 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.
Leeds Analysis: A Further Step Towards Survival
After memorable victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.

The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any prolonged period.

It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
For a short moment, The home ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for Daniel Farke and Leeds to deal with.
