Key Moments
- Dominic Calvert-Lewin watches a first-half header come back off the post.
- Aaronson puts the home side ahead with a well-placed finish in the second period.
- Matheus Cunha levels just three minutes later.
- Leeds extend their longest top-flight undefeated streak since 2001.
The Red Devils' disappointing run of form continued 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.
The Everton loanee directed a first-half attempt against the post for the confident hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had failed to beat bottom-of-the-table Wolves at home earlier in the week.
Nevertheless, against opponents who had two days less to recover, the forward levelled three minutes later when he ran on to a through ball from introduced the Dutchman and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and national team commitments.
Not that you would expect Leeds to care about that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also blasted against a post in the dying moments.
The point extends the home side's unbeaten run to seven games, their longest such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, 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 skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other attackers is having on Amorim's squad.
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 poor results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost immediately 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 preferred positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous struggling signings, lacking in belief and conviction in front of goal.
His 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 Survival
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of expected fervor, but the hostile edge was not as pronounced as in previous fixtures.
The home fans were more concerned about their side's inability to get sustained possession in advanced areas for any length of time.
The striker's header that clipped 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' delirious fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's position.
In contrast, he is now overseeing clear progress.
The task is not done yet but gradually, Leeds are getting closer to achieving their top-flight status.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also beginning their cup journey with a Old Trafford tie.
