Key Moments
- Dominic Calvert-Lewin sees a early header come back off the upright.
- Aaronson puts the home side ahead with a well-placed strike in the second period.
- Cunha equalises only three minutes later.
- Leeds continue their best top-flight unbeaten run since 2001.
Manchester United's disappointing run of form persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for the team not suffering even more damage against Leeds.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the confident home team before Brenden Aaronson finished superbly with a driven, 62nd-minute effort.
With the goal, the United boss was under intense scrutiny after his side had been held by struggling Wolves at home earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha levelled three minutes later when he latched onto a through ball from substitute Joshua Zirkzee and guided a shot underneath rushing 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 the manager is without four 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.
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 the Slovenian striker, who is struggling to make an impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The point prolongs the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations 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 attackers 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 experienced poor results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He clearly does not trust youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds Analysis: Another Step Towards Survival
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of typical atmosphere, 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 prolonged period.
The Calvert-Lewin 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.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now overseeing significant improvement.
The job is not done yet but step by step, the team are getting closer to achieving their survival.
