At a Glance
- Calvert-Lewin watches a early header ricochet off the post.
- Aaronson fires the hosts ahead with a low finish in the second half.
- Matheus Cunha levels just three minutes afterwards.
- Leeds continue their best top-flight unbeaten run since 2001.
Manchester United's poor recent struggles persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the confident hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against opponents who had two days less to prepare, Cunha levelled three minutes after the opener when he ran on to a pass from substitute the Dutchman and guided a finish underneath advancing 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 Amorim is without four key attacking players due to a combination of injury and international duty.
Not that the hosts to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a diving 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 impression, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The point prolongs Leeds' unbeaten run to seven matches, 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, wasted.
Manchester United Breakdown: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team's options.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that suffered poor results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous struggling signings, lacking in belief and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the hostile edge was not as pronounced as in other fixtures.
Leeds' fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were struggling when a defensive error opened the door for the opener.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's future.
In contrast, he is now masterminding significant progress.
The task is not done yet but gradually, Leeds are getting closer to securing their top-flight status.
What Happens Next?
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their FA Cup journey with a home tie.
