Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson fires the hosts ahead with a low strike in the second period.
- Matheus Cunha responds just three minutes later.
- The Yorkshire side continue their longest Premier League unbeaten run since the turn of the century.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
The Everton loanee headed a first-period effort against the woodwork for the in-form home team before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, the United boss was in the firing line after his side had failed to beat 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 pass from substitute the Dutchman and slid a shot underneath rushing home 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 several key attacking players due to a mix of injury and national team commitments.
Not that the hosts to sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, 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 eight points clear of the drop zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the AFCON reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim'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 poor results earlier in the season.
But without them, Amorim has few attacking options.
He clearly does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward delivered the assist for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the expensive frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
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 intimidating edge was not as pronounced as in previous fixtures.
The home fans were more preoccupied about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for the opener.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's position.
In contrast, he is now masterminding clear progress.
The task is not done yet but gradually, the team 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 entering their FA Cup journey with a home tie.
