Key Moments
- Calvert-Lewin sees a first-half header ricochet off the post.
- Brenden Aaronson fires the home side ahead with a well-placed strike in the second period.
- Cunha equalises only three minutes later.
- Leeds extend their longest top-flight undefeated streak 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 damage against Leeds.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
With the goal, the United boss was in the firing line after his side had failed to beat bottom-of-the-table Wolves at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward restored parity three minutes after the opener when he ran on to a through ball from substitute Joshua Zirkzee and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth 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 you would expect the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting 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 ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The point prolongs 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 visitors though, it was yet another opportunity 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 involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's squad.
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 experienced disappointing results earlier in the campaign.
But without them, Amorim has few attacking options.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in belief and assurance in front of goal.
Sesko's 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 thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of typical fervor, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more concerned about their side's inability to get sustained possession in dangerous areas for any length of time.
The striker's header that struck the post was an rare moment of threat 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 delirious fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's future.
Instead, he is now overseeing significant progress.
The task is not completed yet but step by step, Leeds are getting nearer to securing their top-flight status.
Looking Ahead
Leeds 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 league trip to Turf Moor before also beginning their FA Cup journey with a home tie.
