Match Summary
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Brenden Aaronson fires the home side ahead with a well-placed strike in the second period.
- Cunha responds just three minutes later.
- The Yorkshire side extend their longest top-flight undefeated streak since 2001.
The Red Devils' disappointing run of form persisted at Elland Road, but manager 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 woodwork for the in-form hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had been held by struggling Wolves at home earlier in the week.
However, against opponents who had two days less to recover, Cunha levelled three minutes after the opener when he ran on to a pass from introduced Joshua Zirkzee and slid a shot underneath advancing home 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 mix of injury and international duty.
Not that you would expect Leeds to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a audacious 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 six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw extends the home side's unbeaten run to seven matches, their longest such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, squandered.
Man Utd Analysis: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's squad.
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 season.
But without them, the boss has few attacking options.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost instantly after his introduction as a replacement.
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.
Sesko's 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 last few home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were instances of expected fervor, but the hostile edge was not as pronounced as in previous fixtures.
Leeds' fans were more concerned about their side's inability to get sustained possession in advanced areas for any length of time.
The striker's header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context for the manager and the club to deal with.
When they endured a poor run of form earlier in the season, many speculated about the manager's position.
Instead, he is now masterminding clear progress.
The task is not completed yet but step by step, the team are getting closer to securing their survival.
What Happens Next?
The Yorkshire club have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their cup journey with a Old Trafford tie.
