At a Glance
- Calvert-Lewin watches a early header come back off the post.
- Aaronson fires the hosts ahead with a low effort in the second half.
- Matheus Cunha levels just three minutes afterwards.
- The Yorkshire side extend their best top-flight unbeaten run since 2001.
Manchester United's disappointing recent struggles continued at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against their old rivals.
The Everton loanee headed a first-half attempt against the post for the in-form home team before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to recover, Cunha levelled three minutes after the opener when he ran on to a pass from substitute Joshua Zirkzee and guided a shot underneath rushing 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 Amorim is without several key attacking players due to a mix of injury and international duty.
Not that you would expect the hosts to care about that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post in the dying moments.
The draw prolongs the home side's unbeaten run to seven games, their best such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to captain 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 suffered poor results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He clearly does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for the equaliser almost immediately after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Sesko.
On this evidence, the big-money 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 new signing.
Leeds United Breakdown: Another Step Towards Survival
After memorable 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 fervor, but the hostile edge was not as pronounced as in other fixtures.
The home 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 threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for Daniel Farke and the club to deal with.
When they suffered a poor run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now masterminding clear improvement.
The task is not completed yet but step by step, the team are getting closer to securing their top-flight status.
What Happens Next?
The Yorkshire club have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Turf Moor before also beginning their cup journey with a home tie.
