Match Summary
- Dominic Calvert-Lewin watches a first-half header ricochet off the upright.
- Aaronson fires the home side ahead with a low effort in the second period.
- Matheus Cunha equalises just three minutes later.
- Leeds continue their longest top-flight unbeaten run since 2001.
Manchester United's disappointing run of form persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for the team avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the woodwork for the in-form home team before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had been held by struggling Wolves at Old Trafford earlier in the week.
However, against a team who had two days less to prepare, the forward levelled three minutes later when he ran on to a through ball from introduced Joshua Zirkzee and guided a shot underneath rushing home 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 several key attacking players due to a mix of injury and international duty.
Not that Leeds to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, 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 blasted 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 relegation zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other attackers is having on the team's squad.
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 experienced disappointing results earlier in the campaign.
But without them, Amorim has limited attacking options.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost instantly after his arrival as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the young striker.

After memorable victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of expected atmosphere, but the intimidating edge was not as evident as in previous fixtures.
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 the hosts were struggling when a defensive error opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now masterminding clear progress.
The task is not done yet but step by step, the team are getting closer to achieving their survival.
