At a Glance
- Dominic Calvert-Lewin sees a first-half header ricochet off the post.
- Aaronson puts the hosts ahead with a well-placed effort in the second half.
- Matheus Cunha responds only three minutes afterwards.
- The Yorkshire side continue their longest Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more disappointment against Leeds.
The Everton loanee headed a first-period attempt against the post for the confident hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to recover, the forward restored parity three minutes after the opener when he latched onto a through ball from substitute the Dutchman and guided a finish 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 Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United 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 impression, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The draw prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other attackers is having on Amorim'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 disappointing results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in belief and conviction 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 new signing.
Leeds United Breakdown: A Further Step Towards Safety
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 instances of expected atmosphere, but the intimidating edge was not as evident as in previous encounters.
The home fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
However, there is a wider context for the manager and Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now masterminding clear progress.
The job is not completed yet but gradually, Leeds are getting closer to securing their survival.
What Happens Next?
The Yorkshire club have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also entering their FA Cup journey with a home tie.
