Key Moments
- Calvert-Lewin sees a early header ricochet off the post.
- Aaronson puts the hosts ahead with a low effort in the second half.
- Cunha levels only three minutes later.
- Leeds extend their best top-flight unbeaten run since 2001.
Manchester United's disappointing recent struggles persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the post for the confident hosts 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 failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had less time to recover, the forward restored parity three minutes later when he ran on to a pass from substitute Joshua Zirkzee and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and international duty.
Not that you would expect the hosts to care about that given their own tight schedule.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post in the dying moments.
The point extends Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence 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 experienced poor results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He evidently does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as evident as in previous encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for the opener.
Ever so briefly, Leeds' ecstatic 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 suffered a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now overseeing significant improvement.
The task is not completed yet but gradually, Leeds are getting nearer to securing their top-flight status.
What Happens Next?
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their cup journey with a home tie.
