Key Moments
- Calvert-Lewin sees a first-half header come back off the upright.
- Brenden Aaronson puts the hosts ahead with a well-placed finish in the second period.
- Cunha responds only three minutes later.
- Leeds extend their longest Premier League undefeated streak since 2001.
Manchester United's poor run of form persisted at Leeds' fortress, but head coach Ruben Amorim had Matheus Cunha to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin directed a first-period attempt against the woodwork for the confident hosts before the American midfielder finished superbly with a driven, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to recover, the forward levelled three minutes after the opener when he ran on to a pass from substitute the Dutchman and guided a finish underneath rushing Leeds 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 several key attacking players due to a mix of injury and national team commitments.
Not that you would expect Leeds to care about 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 Benjamin Sesko, who is struggling to make an impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the contest, also fired against a post late on.
The point 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 Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other forwards is having on the team's squad.
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 poor results earlier in the season.
But without them, the boss has limited alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money 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 nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Survival
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 hostile edge was not as evident as in other encounters.
The home fans were more concerned about their side's inability to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, 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 thought about the manager's future.
In contrast, he is now overseeing clear progress.
The job is not completed yet but gradually, the team are getting closer to securing their survival.
What Happens Next?
