At a Glance
- Dominic Calvert-Lewin watches a early header come back off the upright.
- Aaronson fires the hosts ahead with a low finish in the second period.
- Cunha equalises only three minutes afterwards.
- The Yorkshire side continue their longest top-flight undefeated streak since 2001.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more disappointment against their old rivals.
The Everton loanee headed a first-half attempt against the post for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against opponents who had two days less to prepare, Cunha restored parity three minutes after the opener when he ran on to a pass from introduced the Dutchman and slid a shot underneath advancing Leeds 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 four key attacking players due to a combination of injury and national team commitments.
Not that you would expect the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also blasted against a post late on.
The point extends the home side's unbeaten run to seven matches, their longest 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 opportunity to move into the Champions League places, albeit only for a short time, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other attackers is having on the team's squad.
It's not that the missing pair are the solution to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, Amorim has limited 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 playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming 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 Analysis: A Further Step Towards Safety
After thrilling victories in their last few 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 advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated 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 the opener.
For a short moment, The home ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now masterminding clear improvement.
The job is not completed yet but gradually, the team are getting closer to securing their survival.
