Match Summary
- Dominic Calvert-Lewin sees a early header ricochet off the upright.
- Brenden Aaronson puts the hosts ahead with a low effort in the second period.
- Matheus Cunha levels just three minutes later.
- The Yorkshire side extend their best top-flight undefeated streak since 2001.
The Red Devils' poor run of form continued at Leeds' fortress, but manager 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 attempt against the post for the confident hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by struggling Wolves at home earlier in the week.
However, against opponents 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 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 the manager is without four key attacking players due to a mix of injury and national team commitments.
Not that the hosts to care about 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 visiting 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 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 point extends the home side's unbeaten run to seven games, their longest such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other attackers 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 attacking options.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the assist for Cunha's equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks no better than previous struggling signings, lacking in confidence and assurance 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 United Breakdown: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of expected atmosphere, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more preoccupied about their side's inability 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 congested first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the season, many speculated about the manager's position.
Instead, he is now masterminding significant improvement.
The job is not done yet but gradually, Leeds are getting closer to achieving their survival.
Looking Ahead
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their FA Cup journey with a home tie.
