Key Moments
- Calvert-Lewin sees a early header come back off the post.
- Brenden Aaronson fires the home side ahead with a low effort in the second period.
- Cunha equalises only three minutes afterwards.
- The Yorkshire side extend their longest top-flight unbeaten run since the turn of the century.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more disappointment against Leeds.
The Everton loanee headed a first-period attempt against the post for the in-form home team before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, the United boss was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolves at home earlier in the week.
Nevertheless, against a team who had less time to prepare, the forward levelled three minutes after the opener when he ran on to a through ball from introduced Joshua Zirkzee and slid a shot underneath advancing 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 international duty.
Not that Leeds to care about that given their own tight schedule.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post late on.
The point extends Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them eight points 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 matter of hours, wasted.
Man Utd Analysis: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers is having on the team'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 season.
But without them, the boss has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of expected fervor, but the intimidating edge was not as evident as in other encounters.
The home fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an rare moment of threat 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, Leeds' delirious fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's future.
In contrast, he is now masterminding significant progress.
The task is not done yet but step by step, Leeds are getting closer to achieving their top-flight status.
What Happens Next?
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also beginning their FA Cup journey with a home tie.
