At a Glance
- Dominic Calvert-Lewin sees a first-half header come back off the upright.
- Aaronson fires the hosts ahead with a well-placed effort in the second half.
- Cunha levels only three minutes later.
- The Yorkshire side extend their longest Premier League unbeaten run since 2001.
Manchester United's poor recent struggles persisted at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more disappointment against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the woodwork for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to recover, the forward levelled three minutes later when he latched onto a through ball from introduced Joshua Zirkzee and guided a shot underneath advancing 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 Amorim is without several key attacking players due to a combination of injury and international duty.
Not that Leeds to care about that given their own lack of preparation time.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The point prolongs the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a short time, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on Amorim's options.
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 suffered disappointing results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He evidently does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for the equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their natural positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were instances of expected atmosphere, but the intimidating edge was not as pronounced as in other fixtures.
The home fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any length of time.
The striker's header that struck the post was an rare moment of threat in a congested 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.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many speculated about the manager's future.
Instead, he is now masterminding significant progress.
The job is not completed yet but step by step, Leeds are getting nearer to achieving their top-flight status.
What Happens Next?
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
