Key Moments
- Calvert-Lewin watches a early header come back off the upright.
- Aaronson fires the hosts ahead with a low strike in the second period.
- Cunha levels just three minutes afterwards.
- The Yorkshire side continue their longest Premier League undefeated streak since 2001.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against Leeds.
The Everton loanee headed a first-period effort against the post for the in-form home team before the American midfielder applied a cool finish with a low, 62nd-minute shot.
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.
However, against a team who had less time to prepare, Cunha levelled three minutes later when he ran on to a pass from introduced Joshua Zirkzee and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League 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 international duty.
Not that the hosts to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed 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 matches, their longest such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the participating nations make a swift exit.
Current injuries to skipper 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 the club's problems. After all, they were part of the side that suffered disappointing results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost immediately after his introduction 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 Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in confidence 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 United Breakdown: Another 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 atmosphere, but the intimidating edge was not as pronounced as in other fixtures.
The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin 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 the opener.
Ever so briefly, 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 difficult run of form earlier in the campaign, many thought about the manager's position.
Instead, he is now overseeing significant improvement.
The job is not done yet but step by step, Leeds are getting closer to achieving their top-flight status.
What Happens Next?
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also entering their FA Cup journey with a home tie.
