Key Moments
- Calvert-Lewin sees a first-half header come back off the upright.
- Aaronson puts the home side ahead with a well-placed finish in the second period.
- Cunha responds only three minutes later.
- Leeds extend their best top-flight undefeated streak since 2001.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more disappointment against Leeds.
Dominic Calvert-Lewin directed a first-half effort against the woodwork for the confident hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had less time to prepare, the forward levelled three minutes later when he latched onto 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 Premier League goal since his big-money summer move and came at a time when Amorim is without four key attacking players due to a mix of injury and national team commitments.
Not that you would expect the hosts to sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length 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 impact, turned his teammate's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post late on.
The point prolongs the home side's unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability 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 disappointing results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He evidently 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 introduction as a substitute.
That leaves Cunha, who has now scored three goals 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 underwhelming signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home the cross means it is now nine games 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 fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of typical atmosphere, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The striker's header that clipped the post was an rare moment of threat in a tight first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, 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 campaign, many thought about the manager's position.
Instead, he is now overseeing significant progress.
The task is not completed yet but gradually, Leeds are getting nearer to achieving their top-flight status.
Looking Ahead
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also beginning their cup journey with a home tie.
