At a Glance
- Dominic Calvert-Lewin watches a early header ricochet off the post.
- Brenden Aaronson fires the hosts ahead with a well-placed effort in the second period.
- Cunha responds just three minutes afterwards.
- Leeds extend their longest Premier League undefeated streak since 2001.
The Red Devils' disappointing recent struggles continued 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 headed 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, Amorim was in the firing line after his side had been held by struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to prepare, the forward restored parity three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and guided a shot 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 Amorim is without several key attacking players due to a combination of injury and international duty.
Not that the hosts to care about that given their own tight schedule.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, 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 longest 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 the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a swift exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on the team's options.
It's not that the missing pair 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, the boss has limited attacking options.
He evidently does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of typical fervor, but the intimidating edge was not as evident as in other fixtures.
Leeds' fans were more concerned about their side's inability to get sustained possession in advanced areas for any prolonged period.
The striker's 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 defensive error opened the door for Aaronson.
Ever so briefly, 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 the club to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's future.
In contrast, he is now overseeing significant improvement.
The task is not done yet but step by step, the team are getting closer to achieving their top-flight status.
