At a Glance
- Dominic Calvert-Lewin watches a early header come back off the post.
- Aaronson puts the hosts ahead with a well-placed finish in the second half.
- Matheus Cunha levels just three minutes later.
- The Yorkshire side extend their longest Premier League undefeated streak 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 his side not suffering even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-half effort 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 under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had two days less to prepare, the forward levelled three minutes after the opener when he latched onto a pass from introduced the Dutchman and guided a finish underneath advancing home 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 Amorim is without several key attacking players due to a combination of injury and international duty.
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 spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The point prolongs the home side's unbeaten run to seven matches, 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 chance to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on the team'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 poor results earlier in the season.
But without them, Amorim has limited attacking options.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost immediately after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous underwhelming signings, lacking in belief and conviction 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 United Breakdown: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the intimidating edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
For a short moment, The home delirious fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the season, many speculated about the manager's position.
Instead, he is now masterminding significant improvement.
The job is not done yet but gradually, Leeds are getting closer to achieving their top-flight status.
Looking Ahead
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their domestic 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.
