Match Summary
- Calvert-Lewin watches a early header come back off the upright.
- Aaronson fires the hosts ahead with a well-placed strike in the second period.
- Matheus Cunha equalises just three minutes later.
- The Yorkshire side extend their longest Premier League unbeaten run since the turn of the century.
Manchester United's disappointing run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post for the confident home team before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
At that stage, the United boss was in the firing line after his side had been held by struggling Wolves at home earlier in the week.
Nevertheless, against a team who had less time to prepare, Cunha levelled three minutes after the opener when he ran on to a through ball from substitute Joshua Zirkzee and slid a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money summer move and came at a time when Amorim is without four key attacking players due to a combination of fitness issues and national team commitments.
Not that you would expect the hosts to sympathise with 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 United heads were in hands when Benjamin Sesko, who is struggling to make an impression, turned his teammate's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the match, also blasted against a post late on.
The point extends 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 Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated 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 experienced disappointing results earlier in the campaign.
But without them, Amorim has limited attacking options.
He evidently does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost instantly after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as evident as in other fixtures.
Leeds' 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 struck the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a wider context for Daniel Farke and the club to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's position.
Instead, he is now overseeing clear progress.
The task is not done yet but step by step, the team are getting closer to achieving their survival.
What Happens Next?
Leeds have a top-flight trip to St James' Park 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 FA Cup journey with a home tie.
