Key Moments
- Dominic Calvert-Lewin watches a early header come back off the post.
- Aaronson puts the hosts ahead with a low effort in the second half.
- Cunha responds just three minutes afterwards.
- Leeds extend their longest Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for the team avoiding even more damage against Leeds.
The Everton loanee directed a first-half effort against the woodwork for the confident hosts before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
With the goal, the United boss was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had two days less to prepare, Cunha restored parity three minutes after the opener when he ran on to a pass from substitute Joshua Zirkzee and guided a shot underneath advancing 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 four key attacking players due to a combination of injury and international duty.
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 Benjamin Sesko, who is struggling to make an impression, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The point extends Leeds' unbeaten run to seven games, 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 chance to move into the Champions League places, albeit only for a matter of hours, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team's options.
It's not that the absent players are the answer 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, the boss has limited alternatives in attack.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others operating out of their natural positions, alongside 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: A Further Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as pronounced as in previous encounters.
The home fans were more concerned about their side's inability to get worthwhile possession in dangerous areas for any length of time.
The striker's header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for the opener.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a wider context for the manager 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 masterminding clear progress.
The task is not done yet but step by step, Leeds are getting closer to securing their survival.
What Happens Next?
Leeds have a Premier League trip to St James' Park 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 cup journey with a home tie.
