Match Summary
- Calvert-Lewin watches a early header ricochet off the post.
- Aaronson puts the home side ahead with a well-placed finish in the second half.
- Matheus Cunha equalises just three minutes later.
- The Yorkshire side continue their longest top-flight undefeated streak since 2001.
The Red Devils' poor run of form persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
The Everton loanee headed a first-half effort against the woodwork for the confident home team before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had been held by struggling Wolves at home earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha levelled three minutes later when he latched onto a pass from introduced Joshua Zirkzee and guided a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without several key attacking players due to a combination of injury and national team commitments.
Not that you would expect Leeds to sympathise with that given their own tight schedule.
Noah Okafor 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 close range.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The point 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 chance to move into the Champions League places, albeit only for a matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a swift exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's options.
It's not that the absent players are the answer to all of United'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 Dutch forward provided the through ball for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of typical fervor, but the hostile edge was not as pronounced as in other encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The striker's header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were struggling when a defensive error opened the door for the opener.
For a short moment, The home delirious fans thought they were about to secure a rare win against Manchester United.
However, there is a wider context for Daniel Farke and the club to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's future.
In contrast, he is now masterminding significant progress.
The task is not completed yet but gradually, Leeds are getting nearer to securing their survival.
