Key Moments
- Calvert-Lewin sees a early header come back off the post.
- Aaronson puts the home side ahead with a well-placed effort in the second half.
- Cunha equalises only three minutes later.
- Leeds extend their longest Premier League unbeaten run since the turn of the century.
The Red Devils' disappointing run of form continued at Leeds' fortress, but manager Ruben Amorim had Matheus Cunha to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had two days less to prepare, Cunha restored parity three minutes later when he latched onto a through ball from introduced Joshua Zirkzee and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a mix 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 audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned his teammate's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post in the dying moments.
The point prolongs the home side's unbeaten run to seven games, their longest 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 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 AFCON reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a swift exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other attackers is having on the team's options.
It's not that the missing pair 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 limited alternatives in attack.
He evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in belief and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were instances of typical fervor, but the hostile edge was not as pronounced as in previous encounters.
The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The striker's header that clipped the post was an isolated moment of threat in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the season, many speculated about the manager's future.
In contrast, he is now overseeing significant progress.
The task is not completed yet but step by step, Leeds are getting nearer to achieving their top-flight status.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
