Key Moments
- Calvert-Lewin watches a early header come back off the upright.
- Aaronson puts the home side ahead with a low finish in the second half.
- Cunha responds just three minutes afterwards.
- The Yorkshire side extend their best top-flight undefeated streak since 2001.
The Red Devils' disappointing run of form persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against Leeds.
The Everton loanee directed a first-half attempt against the post for the in-form hosts before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
However, against opponents who had less time to prepare, the forward restored parity three minutes after the opener when he latched onto a pass from substitute Joshua Zirkzee and guided a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League 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 the hosts to care about that given their own lack of preparation time.
The Swiss attacker forced a diving save out of visiting 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 impact, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The point extends 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 drop 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 AFCON reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on Amorim's options.
It's not that the missing pair are the answer to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He evidently does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds Analysis: Another Step Towards Safety
After memorable victories in their last few home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were instances of typical fervor, but the hostile edge was not as evident as in previous fixtures.
The home fans were more preoccupied 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 rare moment of threat in a tight first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they endured a poor run of form earlier in the season, many speculated about the manager's future.
Instead, he is now overseeing significant progress.
The job is not completed yet but gradually, Leeds are getting nearer to achieving their survival.
Looking Ahead
Leeds 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 league trip to Turf Moor before also entering their FA Cup journey with a home tie.
