At a Glance
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Aaronson puts the hosts ahead with a well-placed finish in the second period.
- Matheus Cunha levels only three minutes afterwards.
- Leeds continue their longest Premier League unbeaten run since the turn of the century.
The Red Devils' poor run of form persisted at Elland Road, but head coach the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post for the in-form home team before Brenden Aaronson applied a cool finish with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to prepare, the forward levelled three minutes later when he latched onto a pass from substitute the Dutchman and guided a finish underneath rushing home goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and national team commitments.
Not that Leeds to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, 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 ruled out for offside much earlier in the match, also blasted against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven games, their best such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other attackers is having on Amorim's squad.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the campaign.
But without them, Amorim has few attacking options.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds Analysis: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more concerned about their side's inability to get worthwhile possession in dangerous areas for any length of time.
The striker's header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now masterminding clear improvement.
The job is not done yet but gradually, Leeds are getting closer to achieving their survival.
What Happens Next?
The Yorkshire club have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also beginning their FA Cup journey with a home tie.
