Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson puts the hosts ahead with a low strike in the second half.
- Matheus Cunha equalises just three minutes afterwards.
- Leeds continue their best Premier League unbeaten run since the turn of the century.
The Red Devils' poor run of form continued at Elland Road, 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 post for the in-form home team before the American midfielder finished superbly with a driven, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to recover, the forward restored parity three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and slid a shot 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 the manager is without several key attacking players due to a mix of fitness issues and international duty.
Not that the hosts to sympathise with 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 the Slovenian striker, who is finding it hard to make an impact, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The draw extends the home side's unbeaten run to seven matches, their best such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a swift exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team's options.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, the boss has limited alternatives in attack.
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 arrival as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive 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 nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the hostile edge was not as pronounced as in other fixtures.
The home fans were more concerned about their side's inability to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now overseeing significant improvement.
The task is not completed yet but step by step, the team are getting closer to securing their top-flight status.
What Happens Next?
The Yorkshire club have a top-flight 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 FA Cup journey with a home tie.
