Key Moments
- Calvert-Lewin sees a first-half header come back off the upright.
- Aaronson puts the home side ahead with a low strike in the second half.
- Matheus Cunha levels only three minutes later.
- Leeds extend their best top-flight undefeated streak since the turn of the century.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for the team not suffering 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 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 two days less to recover, the forward restored parity three minutes later when he ran on to a pass from substitute the Dutchman and guided a finish 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 the manager is without four key attacking players due to a mix of injury and international duty.
Not that you would expect the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the match, also blasted against a post in the dying moments.
The point prolongs the home side's unbeaten run to seven games, their longest such streak since 2001, 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, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team's options.
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 suffered poor results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost instantly 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 natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as pronounced as in other encounters.
Leeds' fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin header that clipped the post was an rare moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for the opener.
For a short moment, Leeds' 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 endured a poor run of form earlier in the season, many speculated about the manager's future.
Instead, he is now overseeing clear improvement.
The task is not done yet but step by step, Leeds are getting closer to securing their top-flight status.
