At a Glance
- Dominic Calvert-Lewin watches a first-half header ricochet off the post.
- Aaronson fires the hosts ahead with a well-placed strike in the second period.
- Matheus Cunha responds only three minutes later.
- The Yorkshire side continue their longest Premier League undefeated streak since the turn of the century.
Manchester United's poor recent struggles continued at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-period effort against the woodwork for the in-form hosts before the American midfielder finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had been held by struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha levelled three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and guided a shot underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his big-money 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 Leeds to sympathise with that given their own tight schedule.
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 struggling to make an impact, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also fired against a post late on.
The draw extends Leeds' 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 the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's options.
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 clearly does not trust youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost immediately 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 preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in belief and conviction 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 Analysis: Another Step Towards Survival
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of typical fervor, but the intimidating edge was not as evident as in previous encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
For a short moment, The home delirious fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now masterminding clear progress.
The task is not completed yet but gradually, the team are getting closer to achieving their top-flight status.
What Happens Next?
The Yorkshire club 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 beginning their FA Cup journey with a home tie.
