At a Glance
- Calvert-Lewin sees a first-half header come back off the upright.
- Brenden Aaronson puts the home side ahead with a low effort in the second half.
- Matheus Cunha responds just three minutes later.
- The Yorkshire side extend their longest Premier League undefeated streak since 2001.
Manchester United's disappointing run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the woodwork for the in-form home team before the American midfielder finished superbly with a low, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had less time to prepare, Cunha levelled three minutes later 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 goal since his high-profile summer move and came at a time when the manager is without several key attacking players due to a combination of injury and national team commitments.
Not that you would expect the hosts to care about that given their own tight schedule.
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 the Slovenian striker, 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 contest, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's squad.
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 experienced disappointing results earlier in the season.
But without them, the boss has few alternatives in attack.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of typical fervor, but the intimidating edge was not as pronounced as in previous encounters.
Leeds' fans were more preoccupied about their side's inability to get worthwhile possession in advanced 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 struggling when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a wider context for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the campaign, many thought about the manager's position.
Instead, he is now overseeing significant improvement.
The task is not done yet but step by step, the team are getting closer to securing their top-flight status.
What Happens Next?
Leeds 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 Burnley before also entering their FA Cup journey with a home tie.
