At a Glance
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-half attempt against the post for the in-form hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute effort.
At that stage, the United boss was in the firing line after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had less time to recover, Cunha levelled three minutes after the opener when he ran on to a through ball from substitute the Dutchman and slid a finish underneath rushing home 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 Amorim is without four key attacking players due to a combination of fitness issues and national team commitments.
Not that the hosts to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting 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 Zirkzee'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 prolongs the home side's unbeaten run to seven games, their longest such streak since 2001, 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 short time, squandered.
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on the team's squad.
It's not that the absent players are the answer 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, Amorim has few alternatives in attack.
He evidently does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, 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 belief and conviction in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the young striker.
After memorable victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of typical atmosphere, but the hostile edge was not as pronounced as in other encounters.
The home fans were more preoccupied 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 quality in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
For a short moment, The home delirious fans thought they were about to secure a coveted win against their old foes.
However, there is a wider context for Daniel Farke and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now overseeing clear progress.
The job is not done yet but gradually, Leeds are getting closer to securing their survival.
Leeds have a Premier League trip to St James' Park 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 FA Cup journey with a home tie.
