Match Summary
- Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson puts the hosts ahead with a well-placed finish in the second period.
- Matheus Cunha levels only three minutes later.
- Leeds continue their best Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against Leeds.
The Everton loanee headed a first-half effort against the woodwork for the confident hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had less time to prepare, the forward levelled three minutes later when he latched onto a through ball from substitute Joshua Zirkzee and guided a shot underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a mix of fitness issues and national team commitments.
Not that the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a full length 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 close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The point extends the home side's unbeaten run to seven games, 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 chance to move into the Champions League places, albeit only for a matter of hours, squandered.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be forgiven for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence 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 suffered disappointing results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous struggling 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 new signing.
Leeds Analysis: A Further Step Towards Safety
After memorable 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 intimidating edge was not as pronounced as in previous fixtures.
The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The striker's header that clipped the post was an rare moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context for the manager and the club to deal with.
When they suffered a poor run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now masterminding significant improvement.
The job is not done yet but gradually, the team are getting nearer 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. Manchester United face a league trip to Turf Moor before also beginning their cup journey with a home tie.
