Key Moments
- Calvert-Lewin watches a first-half header ricochet off the post.
- Brenden Aaronson fires the hosts ahead with a well-placed finish in the second period.
- Matheus Cunha equalises only three minutes later.
- Leeds continue their best top-flight unbeaten run since the turn of the century.
The Red Devils' poor run of form continued at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the post for the in-form hosts before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to prepare, Cunha restored parity three minutes later when he ran on to a pass from substitute the Dutchman and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American'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 national team commitments.
Not that you would expect Leeds to care about that given their own tight schedule.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The point extends Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into fourth spot, 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 participating nations make a swift exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on the team's options.
It's not that the missing pair are the solution to all of the club's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, Amorim has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others playing out of their natural positions, alongside Sesko.
On this showing, 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 Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their last few home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of expected fervor, but the intimidating edge was not as evident as in previous fixtures.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin 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 the opener.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
However, there is a much bigger picture for Daniel Farke and the club to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's position.
In contrast, he is now overseeing significant progress.
The task is not completed yet but step by step, the team are getting closer to securing their top-flight status.
Looking Ahead
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Burnley before also beginning their FA Cup journey with a home tie.
