Key Moments
- Calvert-Lewin sees a first-half header come back off the upright.
- Aaronson fires the hosts ahead with a well-placed strike in the second period.
- Cunha equalises just three minutes afterwards.
- The Yorkshire side extend their best Premier League undefeated streak since the turn of the century.
The Red Devils' poor run of form persisted at Elland Road, but manager the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more disappointment against Leeds.
Dominic Calvert-Lewin directed a first-period effort against the woodwork for the in-form hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had two days less to recover, the forward levelled three minutes after the opener when he latched onto a through ball from substitute Joshua Zirkzee and guided a shot 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 the manager is without several key attacking players due to a combination of injury and national team commitments.
Not that the hosts to care about that given their own lack of preparation time.
The Swiss attacker forced a diving save out of Manchester United 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 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 blasted against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, squandered.
Man Utd Analysis: The Manager's Side Struggle 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 captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers is having on Amorim's squad.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, the boss has few attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in recent outings, and others operating out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After memorable victories in their last few home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of typical fervor, but the intimidating edge was not as pronounced as in other fixtures.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
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.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's future.
In contrast, he is now masterminding clear progress.
The job is not completed yet but gradually, Leeds are getting closer to securing their survival.
Looking Ahead
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Burnley before also beginning their cup journey with a Old Trafford tie.
