Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Brenden Aaronson puts the home side ahead with a well-placed effort in the second period.
- Cunha responds just three minutes later.
- Leeds continue their longest top-flight undefeated streak since 2001.
The Red Devils' poor run of form continued at Leeds' fortress, but manager Ruben Amorim had Matheus Cunha to thank for his side not suffering even more damage against their old rivals.
The Everton loanee headed a first-half attempt against the woodwork for the confident home team before the American midfielder applied a cool finish with a low, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
However, against a team who had two days less to prepare, the forward levelled three minutes after the opener when he ran on to a through ball from substitute the Dutchman and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a combination of fitness issues and international duty.
Not that Leeds 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 audacious overhead kick, and United heads were in hands when the Slovenian striker, 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 ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw prolongs 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 drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on Amorim's options.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He clearly does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and conviction 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 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 fervor, but the hostile edge was not as pronounced as in previous fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The striker's header that struck the post was an rare moment of threat in a tight first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a wider context for Daniel Farke and the club 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 overseeing clear progress.
The task is not completed yet but step by step, Leeds are getting closer to securing their survival.
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. Manchester United face a Premier League trip to Burnley before also entering their cup journey with a home tie.
