Match Summary
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson puts the home side ahead with a well-placed effort in the second half.
- Cunha levels just three minutes later.
- Leeds continue their best top-flight unbeaten run since 2001.
The Red Devils' poor run of form continued at Elland Road, but head coach the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more disappointment against Leeds.
The Everton loanee directed a first-half attempt against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against a team who had less time to prepare, Cunha restored parity three minutes later when he ran on to a pass from substitute the Dutchman and slid a finish underneath rushing home goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a combination of injury and national team commitments.
Not that you would expect Leeds to sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length save out of visiting 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 six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The draw extends the home side's unbeaten run to seven matches, their longest 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 the Champions League places, albeit only for a matter of hours, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, the United coach could be understood for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability 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 suffered poor results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He evidently does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the assist for the equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds Analysis: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of typical 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 sustained possession in dangerous areas for any prolonged period.
The striker's header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now overseeing clear improvement.
The job is not completed yet but gradually, the team are getting nearer to securing their top-flight status.
Looking Ahead
The Yorkshire club have a top-flight 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 Turf Moor before also entering their FA Cup journey with a home tie.
