At a Glance
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Aaronson fires the hosts ahead with a low finish in the second period.
- Cunha responds only three minutes later.
- Leeds continue their best Premier League unbeaten run since 2001.
The Red Devils' poor recent struggles continued at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
The Everton loanee directed a first-period effort against the woodwork for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had less time to prepare, the forward levelled three minutes after the opener when he ran on to a pass from substitute the Dutchman and slid 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 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 lack of preparation time.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling 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 contest, also blasted against a post in the dying moments.
The point extends the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, wasted.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on Amorim's options.
It's not that the absent players are the answer to all of United's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, 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 struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds Analysis: Another Step Towards Survival
After memorable victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the intimidating 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 length of time.
The striker's header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were struggling when a defensive error opened the door for Aaronson.
For a short moment, The home delirious fans thought they were about to secure a coveted win against their old foes.
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 campaign, many thought about the manager's position.
In contrast, he is now masterminding clear improvement.
The job is not done yet but gradually, Leeds are getting closer to securing their survival.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also beginning their cup journey with a home tie.
