Match Summary
- Dominic Calvert-Lewin watches a first-half header come back off the upright.
- Aaronson fires the hosts ahead with a low strike in the second half.
- Matheus Cunha responds only three minutes later.
- Leeds continue their longest top-flight unbeaten run since 2001.
The Red Devils' disappointing run of form continued at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more disappointment against Leeds.
The Everton loanee headed a first-half effort against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
However, against opponents who had two days less to prepare, the forward levelled three minutes after the opener when he ran on to a pass from substitute the Dutchman and slid a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth 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 injury and international duty.
Not that Leeds to care about that given their own tight schedule.
The Swiss attacker 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 struggling to make an impression, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The draw extends the home side's unbeaten run to seven matches, their best such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on Amorim's squad.
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 poor results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further 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 instances of expected fervor, but the intimidating edge was not as evident as in other encounters.
The home fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated moment of threat in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's future.
Instead, he is now overseeing significant improvement.
The job is not done yet but step by step, the team are getting closer to achieving their top-flight status.
Looking Ahead
The Yorkshire club 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 entering their FA Cup journey with a Old Trafford tie.
