Key Moments
- Dominic Calvert-Lewin sees a early header come back off the post.
- Aaronson fires the hosts ahead with a low finish in the second period.
- Matheus Cunha levels just three minutes afterwards.
- Leeds extend their best Premier League unbeaten run since the turn of the century.
The Red Devils' poor run of form persisted at Leeds' fortress, but manager Ruben Amorim had Matheus Cunha to thank for the team avoiding even more disappointment against Leeds.
The Everton loanee directed a first-period effort against the woodwork for the confident hosts before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, the United boss was in the firing line after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward levelled three minutes later when he latched onto a pass from introduced Joshua Zirkzee and slid a finish underneath advancing 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 several key attacking players due to a mix of fitness issues and national team commitments.
Not that you would expect Leeds to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post late on.
The point extends Leeds' unbeaten run to seven games, their best such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the participating nations make a swift exit.
Current 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 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, Amorim has few attacking options.
He clearly does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous struggling 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 United Breakdown: A Further Step Towards Safety
After thrilling victories in their last few home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as pronounced as in other fixtures.
Leeds' fans were more concerned 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 rare moment of threat in a tight first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for Aaronson.
For a short moment, The home ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, 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 masterminding significant progress.
The task is not done yet but gradually, the team are getting nearer to securing their survival.
