Key Moments
- Calvert-Lewin sees a first-half header ricochet off the upright.
- Brenden Aaronson fires the home side ahead with a well-placed strike in the second period.
- Cunha equalises only three minutes later.
- The Yorkshire side continue their best Premier League unbeaten run since the turn of the century.
Manchester United's poor recent struggles persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
The Everton loanee directed a first-period effort against the woodwork for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute effort.
With the goal, the United boss was under intense scrutiny after his side had failed to beat struggling Wolves at home earlier in the week.
However, against a team who had less time to prepare, the forward levelled three minutes after the opener when he latched onto a pass from substitute Joshua Zirkzee and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a mix of injury and international duty.
Not that you would expect the hosts to care about that given their own tight schedule.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impression, turned his teammate'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 in the dying moments.
The point prolongs the home side's unbeaten run to seven games, their best such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers is having on Amorim's options.
It's not that the absent players are the answer to all of United's problems. After all, they were part of the side that suffered disappointing results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He evidently does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch 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 five games, and others playing out of their natural positions, alongside Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming 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: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as pronounced as in previous fixtures.
The home 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 struck the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a much bigger picture for Daniel Farke and the club to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's position.
In contrast, he is now masterminding clear progress.
The task is not completed yet but gradually, the team are getting nearer to securing their survival.
What Happens Next?
