Match Summary
- Dominic Calvert-Lewin watches a first-half header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed finish in the second period.
- Matheus Cunha equalises only three minutes later.
- Leeds continue their longest Premier League undefeated streak since 2001.
The Red Devils' poor recent struggles continued at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering 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 driven, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had less time to recover, Cunha levelled three minutes after the opener when he latched onto a pass from introduced the Dutchman and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a combination of injury and international duty.
Not that Leeds to care about that given their own tight schedule.
The Swiss attacker forced a diving 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 match, also blasted against a post in the dying moments.
The point extends the home side's unbeaten run to seven games, their longest such streak since over two decades ago, 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.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other attackers is having on the team's options.
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 experienced poor results earlier in the campaign.
But without them, the boss has limited attacking options.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of typical fervor, but the hostile edge was not as pronounced as in other encounters.
The home fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of threat in a tight first half.
It still felt as though Leeds 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 coveted win against Manchester United.
However, there is a much bigger picture for the manager and the club to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's future.
Instead, he is now masterminding significant improvement.
The task is not completed yet but step by step, the team are getting nearer to achieving their survival.
What Happens Next?
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a Premier League trip to Turf Moor before also beginning their cup journey with a home tie.
