Key Moments
- Dominic Calvert-Lewin watches a first-half header come back off the post.
- Aaronson fires the home side ahead with a low effort in the second period.
- Cunha responds just three minutes later.
- The Yorkshire side extend their best Premier League undefeated streak since the turn of the century.
Manchester United's poor recent struggles persisted at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-half attempt against the post for the in-form hosts before the American midfielder finished superbly with a driven, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had been held by struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to prepare, Cunha restored parity three minutes after the opener when he ran on to a through ball from introduced Joshua Zirkzee and slid a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a mix of fitness issues and international duty.
Not that you would expect Leeds to care about that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also blasted against a post in the dying moments.
The draw extends the home side's unbeaten run to seven games, their best such streak since 2001, and takes them eight points 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.
Manchester United Breakdown: 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.
Existing injuries to captain Bruno Fernandes and England international 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 suffered disappointing results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He clearly does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the new signing.
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 fervor, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more concerned about their side's inability to get sustained possession in dangerous areas for any length of time.
The Calvert-Lewin header that clipped the post was an isolated moment of quality in a congested first half.
It still felt as though the hosts were struggling when a defensive error opened the door for Aaronson.
Ever so briefly, The home ecstatic 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 endured a difficult run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now masterminding clear progress.
The task is not completed yet but step by step, the team are getting closer to securing their survival.
Looking Ahead
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their cup journey with a home tie.
