At a Glance
- Calvert-Lewin sees a early header ricochet off the post.
- Aaronson puts the hosts ahead with a well-placed strike in the second period.
- Cunha equalises only three minutes later.
- The Yorkshire side continue their best top-flight undefeated streak since the turn of the century.
The Red Devils' poor recent struggles persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
The Everton loanee headed a first-half effort against the post for the in-form home team before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
At that stage, 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.
However, against opponents who had less time to recover, Cunha restored parity three minutes after the opener when he ran on to a through ball from introduced Joshua Zirkzee and slid a finish underneath advancing 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 combination of injury and international duty.
Not that the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire 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.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's squad.
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, the boss has few alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous underwhelming signings, lacking in belief 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 new signing.
Leeds Analysis: Another Step Towards Safety
After memorable 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 fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a wider context for Daniel Farke and the club to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's position.
In contrast, he is now masterminding clear progress.
The job is not completed yet but step by step, Leeds are getting nearer to securing their top-flight status.
Looking Ahead
The Yorkshire club have a Premier League 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.
