Match Summary
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Aaronson puts the hosts ahead with a well-placed finish in the second half.
- Cunha levels just three minutes later.
- The Yorkshire side continue their best Premier League unbeaten run since 2001.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more disappointment against Leeds.
Dominic Calvert-Lewin headed a first-half attempt against the post for the confident hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
However, against opponents who had less time to recover, Cunha levelled three minutes later when he latched onto a pass from substitute the Dutchman and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without several key attacking players due to a mix of fitness issues and national team commitments.
Not that Leeds to sympathise with that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The draw prolongs the home side's unbeaten run to seven games, their longest such streak since 2001, 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.
Man Utd Analysis: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim 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 exacerbated the impact the unavailability of other attackers 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 poor results earlier in the season.
But without them, the boss has few attacking options.
He clearly does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in recent outings, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks similar to 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 new signing.
Leeds United Breakdown: A Further Step Towards Survival
After thrilling victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of typical atmosphere, but the hostile edge was not as pronounced as in other fixtures.
Leeds' fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were struggling when a defensive error opened the door for the opener.
Ever so briefly, The home delirious fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a wider context for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the season, many speculated about the manager's future.
Instead, he is now masterminding clear progress.
The task is not completed yet but step by step, the team are getting closer to achieving their top-flight status.
