Match Summary
- Dominic Calvert-Lewin watches a first-half header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed strike in the second half.
- Matheus Cunha levels just three minutes afterwards.
- The Yorkshire side extend their best top-flight unbeaten run since the turn of the century.
The Red Devils' disappointing run of form continued at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more damage against Leeds.
The Everton loanee headed a first-half effort against the post for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had two days less to prepare, the forward levelled three minutes later when he latched onto a through ball from substitute Joshua Zirkzee and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth 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 injury and national team commitments.
Not that you would expect 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 Benjamin Sesko, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted 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 a significant margin 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.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other forwards is having on the team's options.
It's not that the missing pair are the solution to all of the club'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 much more experienced Joshua Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost immediately after his arrival 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 Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in confidence 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 young striker.
Leeds United Breakdown: A Further Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the hostile edge was not as pronounced as in previous encounters.
Leeds' fans were more concerned about their side's inability to get worthwhile possession in advanced 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 defensive error opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for Daniel Farke and the club to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's future.
Instead, he is now masterminding clear progress.
The task is not completed yet but step by step, the team are getting nearer to achieving their top-flight status.
What Happens Next?
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also beginning their cup journey with a Old Trafford tie.
