Match Summary
- Calvert-Lewin sees a first-half header come back off the post.
- Aaronson fires the hosts ahead with a well-placed finish in the second half.
- Matheus Cunha equalises only three minutes afterwards.
- The Yorkshire side continue their longest top-flight undefeated streak since 2001.
The Red Devils' poor run of form continued at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-period attempt against the post for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to prepare, the forward restored parity three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and guided a shot underneath rushing home 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 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 full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's options.
It's not that the missing pair 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 campaign.
But without them, the boss has limited alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of typical fervor, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more preoccupied 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 rare moment of quality in a tight 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 their old foes.
However, there is a much bigger picture for Daniel Farke and the club to deal with.
When they endured a poor run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now masterminding clear progress.
The task is not completed yet but gradually, the team are getting nearer to achieving their survival.
Looking Ahead
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also beginning their FA Cup journey with a home tie.
