Key Moments
- Calvert-Lewin sees a first-half header ricochet off the post.
- Aaronson fires the home side ahead with a well-placed effort in the second half.
- Cunha levels just three minutes afterwards.
- Leeds extend their longest top-flight unbeaten run since the turn of the century.
The Red Devils' poor recent struggles continued at Leeds' fortress, but head coach Ruben Amorim had Matheus Cunha to thank for his side avoiding even more damage against Leeds.
The Everton loanee directed a first-period effort against the woodwork for the confident home team before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had two days less to recover, Cunha restored parity three minutes after the opener when he ran on to a through ball from substitute 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 big-money summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and international duty.
Not that Leeds to care about that given their own tight schedule.
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 Benjamin Sesko, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The point prolongs the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors 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, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other attackers is having on Amorim's options.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, the boss has limited alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced 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 three goals in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the expensive frontman looks similar to previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After memorable victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were instances of expected atmosphere, but the hostile edge was not as pronounced as in previous fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in dangerous 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 Leeds were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against their old foes.
However, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now masterminding clear progress.
The job is not completed yet but step by step, the team are getting closer to securing their survival.
Looking Ahead
The Yorkshire club 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 Burnley before also beginning their cup journey with a home tie.
