At a Glance
- Calvert-Lewin sees a early header ricochet off the post.
- Brenden Aaronson fires the home side ahead with a well-placed effort in the second period.
- Cunha responds only three minutes afterwards.
- Leeds extend their best top-flight unbeaten run since the turn of the century.
The Red Devils' poor run of form continued at Elland Road, but manager the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-period attempt against the woodwork for the confident home team before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward levelled three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a mix of injury and national team commitments.
Not that the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impression, turned his teammate's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The point prolongs Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them eight points 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 matter of hours, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on the team's squad.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Safety
After memorable 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 atmosphere, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more concerned about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an rare moment of quality 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, The home delirious fans thought they were about to secure a coveted win against their old foes.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now overseeing clear improvement.
The task is not done yet but step by step, the team are getting nearer to securing their top-flight status.
What Happens Next?
The Yorkshire club 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 league trip to Turf Moor before also entering their cup journey with a Old Trafford tie.
