Key Moments
- Calvert-Lewin watches a early header ricochet off the post.
- Aaronson fires the home side ahead with a low finish in the second half.
- Cunha equalises just three minutes later.
- The Yorkshire side extend their best Premier League unbeaten run since 2001.
The Red Devils' disappointing run of form continued at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the post for the confident hosts before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had failed to beat bottom-of-the-table Wolves at Old Trafford earlier in the week.
However, against a team who had two days less to prepare, Cunha levelled three minutes after the opener when he ran on to a pass from substitute the Dutchman and guided a shot underneath rushing home 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 mix 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 diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal ruled out 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 a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, wasted.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other attackers is having on Amorim's squad.
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 experienced disappointing results earlier in the campaign.
But without them, the boss has limited attacking options.
He clearly does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in belief and assurance in front of goal.
His 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 Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of typical atmosphere, but the hostile edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in dangerous areas for any length of time.
The Calvert-Lewin header that clipped the post was an rare moment of threat in a tight first half.
It still felt as though the hosts were struggling when a defensive error opened the door for the opener.
For a short moment, The home ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for Daniel Farke and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now overseeing significant progress.
The job is not completed yet but step by step, Leeds are getting nearer to securing their top-flight status.
What Happens Next?
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their FA Cup journey with a home tie.
