At a Glance
- Calvert-Lewin watches a early header ricochet off the post.
- Aaronson puts the hosts ahead with a well-placed strike in the second half.
- Cunha responds just three minutes afterwards.
- The Yorkshire side continue their best top-flight unbeaten run since the turn of the century.
The Red Devils' disappointing run of form continued at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for the team not suffering even more disappointment against Leeds.
Dominic Calvert-Lewin directed a first-half attempt against the post for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against a team who had less time to prepare, the forward restored parity three minutes later when he ran on to a pass from substitute the Dutchman and guided a finish underneath advancing 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 four key attacking players due to a mix of fitness issues and international duty.
Not that you would expect Leeds to care about that given their own lack of preparation time.
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 Benjamin Sesko, 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 draw extends the home side's unbeaten run to seven games, their longest such streak since 2001, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on the team'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 suffered poor results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He evidently does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost immediately after his arrival as a substitute.
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 big-money frontman looks no better than previous underwhelming signings, lacking in confidence and conviction 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 United Breakdown: Another Step Towards Safety
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 expected atmosphere, but the hostile edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The striker's header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for Daniel Farke and the club to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now masterminding clear progress.
The job is not completed yet but step by step, the team are getting closer to securing their top-flight status.
What Happens Next?
The Yorkshire club 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 beginning their cup journey with a home tie.
