Key Moments
- Dominic Calvert-Lewin watches a first-half header come back off the upright.
- Aaronson puts the home side ahead with a low finish in the second period.
- Matheus Cunha responds just three minutes afterwards.
- The Yorkshire side extend their longest top-flight undefeated streak since the turn of the century.
The Red Devils' disappointing run of form continued at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the post for the confident home team before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against a team who had two days less to recover, the forward restored parity three minutes later when he latched onto a through ball from introduced Joshua Zirkzee and guided a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth 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 international duty.
Not that the hosts to care about that given their own tight schedule.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling 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 fired against a post late on.
The draw extends the home side's unbeaten run to seven matches, their best 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, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Existing 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 answer 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 youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their preferred positions, alongside 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 the cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
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 moments of typical fervor, but the hostile edge was not as evident as in previous encounters.
The home fans were more concerned about their side's inability to get sustained possession in dangerous areas for any prolonged period.
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 finding it tough when a defensive error opened the door for Aaronson.
For a short moment, The home delirious fans thought they were about to secure a rare win against their old foes.
However, 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 campaign, many speculated about the manager's position.
Instead, he is now masterminding clear improvement.
The task is not done yet but step by step, Leeds are getting nearer to achieving their top-flight status.
What Happens Next?
Leeds have a Premier League trip to Newcastle 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 beginning their cup journey with a home tie.
