Key Moments
- Calvert-Lewin watches a early header come back off the post.
- Aaronson puts the hosts ahead with a well-placed strike in the second half.
- Matheus Cunha levels only three minutes afterwards.
- The Yorkshire side continue their best Premier League undefeated streak since 2001.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
The Everton loanee directed a first-period attempt against the post for the in-form home team before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against opponents who had less time to prepare, the forward levelled three minutes after the opener when he ran on to a pass from introduced Joshua Zirkzee and guided a finish underneath rushing home goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a combination of fitness issues and national team commitments.
Not that you would expect Leeds 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 Benjamin Sesko, who is struggling to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post late on.
The draw 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 chance to move into fourth spot, albeit only for a matter of hours, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated 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 the club's problems. After all, they were part of the side that suffered poor results earlier in the season.
But without them, Amorim has limited alternatives in attack.
He evidently does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the assist for the equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and conviction 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 United Breakdown: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as pronounced as in other fixtures.
The home fans were more concerned about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The striker's header that clipped the post was an rare moment of quality in a congested first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a much bigger picture for the manager and the club to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's future.
Instead, he is now overseeing significant progress.
The job is not done yet but gradually, the team are getting nearer to achieving their top-flight status.
Looking Ahead
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their cup journey with a home tie.
