Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson puts the home side ahead with a well-placed finish in the second half.
- Matheus Cunha responds only three minutes afterwards.
- Leeds continue their longest top-flight unbeaten run since 2001.
The Red Devils' disappointing recent struggles persisted at Elland Road, but head coach the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the woodwork for the in-form hosts before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against a team who had two days less to prepare, Cunha restored parity three minutes later when he ran on to a through ball from substitute the Dutchman and slid a finish underneath rushing 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 the manager is without several key attacking players due to a combination of injury and national team commitments.
Not that you would expect 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 spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling 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 contest, also fired against a post late on.
The point extends Leeds' unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a short time, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the involved countries make a swift exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on the team'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 suffered poor results earlier in the season.
But without them, Amorim has few attacking options.
He evidently does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, 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 similar to previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds Analysis: Another Step Towards Safety
After memorable victories in their last few 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 previous fixtures.
Leeds' 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 struck the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the campaign, many thought about the manager's position.
Instead, he is now overseeing clear improvement.
The task is not done yet but step by step, Leeds are getting nearer to achieving their survival.
What Happens Next?
The Yorkshire club 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.
