Key Moments
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed finish in the second half.
- Cunha responds just three minutes later.
- Leeds continue their best top-flight undefeated streak since the turn of the century.
The Red Devils' poor recent struggles continued at Elland Road, but head coach Ruben Amorim had Matheus Cunha to thank for the team avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-period attempt against the woodwork for the in-form home team 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 after the opener when he ran on to a through ball from introduced the Dutchman and slid a shot 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 several key attacking players due to a mix of injury and national team commitments.
Not that you would expect the hosts to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United 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 close range.
Cunha, who had a goal ruled out for offside much earlier in the contest, also fired against a post late on.
The draw prolongs Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into fourth spot, 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, the United coach could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on the team's options.
It's not that the missing pair 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 limited alternatives in attack.
He evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in recent outings, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks similar to previous underwhelming signings, lacking in confidence and assurance in front of goal.
Sesko's 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 Survival
After thrilling victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of expected fervor, 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 dangerous areas for any prolonged period.
The striker's header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against Manchester United.
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 season, many speculated about the manager's position.
Instead, he is now masterminding significant improvement.
The task is not done yet but gradually, Leeds are getting nearer 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. The Red Devils face a league trip to Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
