Key Moments
- Dominic Calvert-Lewin sees a early header come back off the upright.
- Aaronson fires the hosts ahead with a well-placed strike in the second half.
- Matheus Cunha levels just three minutes later.
- Leeds continue their longest top-flight unbeaten run since the turn of the century.
Manchester United's disappointing recent struggles continued at Elland Road, but manager Ruben Amorim had Matheus Cunha to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed 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, the United boss was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to recover, Cunha restored parity three minutes after the opener when he latched onto a pass from introduced the Dutchman and guided a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and national team commitments.
Not that you would expect Leeds to care about that given their own tight schedule.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The point extends the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin 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, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, the United coach could be understood for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team'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 season.
But without them, Amorim has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in recent outings, and others playing out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks no better than 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 new signing.
Leeds United Breakdown: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were instances of expected fervor, but the hostile edge was not as pronounced as in other encounters.
The home 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 isolated moment of threat in a congested first half.
It still felt as though Leeds were finding it tough 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 the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's future.
Instead, he is now overseeing clear progress.
The job is not done yet but step by step, the team are getting closer 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 FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their cup journey with a home tie.
