Match Summary
Manchester United's poor run of form continued at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more damage against their old rivals.
The Everton loanee directed a first-period attempt against the woodwork for the confident hosts before the American midfielder applied a cool finish with a low, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had less time to recover, the forward levelled three minutes after the opener when he ran on to a pass from introduced the Dutchman and slid a finish underneath rushing 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 the manager is without four key attacking players due to a combination of fitness issues and national team commitments.
Not that you would expect the hosts 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 the Slovenian striker, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The point prolongs the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a short time, wasted.
With the AFCON reaching its knockout phase, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's options.
It's not that the absent players are the answer 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 few alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the through ball for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Sesko.
On this evidence, the expensive frontman looks no better than previous struggling 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 new signing.
After thrilling 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 preoccupied about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an rare moment of quality in a tight first half.
It still felt as though the hosts were struggling when a defensive error opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for Daniel Farke and the club to deal with.
When they endured a poor run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now overseeing significant improvement.
The task is not done yet but step by step, Leeds are getting closer to securing their top-flight status.
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 Premier League trip to Burnley before also beginning their FA Cup journey with a home tie.
