At a Glance
- Dominic Calvert-Lewin watches a early header ricochet off the post.
- Aaronson fires the hosts ahead with a low finish in the second half.
- Matheus Cunha levels only three minutes afterwards.
- Leeds continue their best Premier League unbeaten run since 2001.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but manager Ruben Amorim had Matheus Cunha to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-half effort against the post for the confident hosts before the American midfielder applied a cool finish with a low, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had two days less to recover, the forward levelled three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and slid a shot underneath rushing Leeds 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 the manager is without four key attacking players due to a mix of injury and national team commitments.
Not that the hosts to care about that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from close range.
The goalscorer, 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 games, their best such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other attackers is having on Amorim'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 experienced disappointing results earlier in the season.
But without them, Amorim has few alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost instantly after his arrival 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 Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home the cross means it is now nine games 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 biggest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of typical atmosphere, but the hostile edge was not as pronounced as in other encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in dangerous areas for any length of time.
The striker's header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's position.
In contrast, he is now overseeing significant progress.
The job is not completed yet but step by step, the team 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 FA Cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also entering their cup journey with a Old Trafford tie.
