At a Glance
- Calvert-Lewin watches a first-half header ricochet off the post.
- Brenden Aaronson fires the hosts ahead with a low finish in the second half.
- Cunha equalises only three minutes later.
- The Yorkshire side continue their longest top-flight unbeaten run since 2001.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but head coach Ruben Amorim had Matheus Cunha to thank for the team not suffering even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-period effort against the post for the in-form hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to prepare, the forward levelled three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a mix of injury and international duty.
Not that you would expect the hosts to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United 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 impression, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw extends the home side's unbeaten run to seven matches, their best such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, wasted.

With the AFCON reaching its latter stages, Amorim could be forgiven for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's squad.
It's not that the absent players 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 season.
But without them, Amorim has limited alternatives in attack.
He evidently does not trust youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the assist for Cunha's equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and assurance 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 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 fervor, but the hostile edge was not as pronounced as in previous fixtures.
The home fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an rare moment of quality in a congested first half.
It still felt as though the hosts were struggling 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 Manchester United.
However, there is a much bigger picture 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 future.
In contrast, he is now overseeing significant progress.
The job is not completed yet but step by step, Leeds are getting nearer to achieving their top-flight status.
Looking Ahead
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their cup journey with a home tie.
