Key Moments
- Dominic Calvert-Lewin watches a early header ricochet off the upright.
- Brenden Aaronson puts the hosts ahead with a well-placed finish in the second half.
- Matheus Cunha equalises only three minutes afterwards.
- The Yorkshire side extend their longest top-flight unbeaten run since the turn of the century.
Manchester United's disappointing run of form continued at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-half effort against the woodwork for the confident home team before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to prepare, the forward restored parity three minutes later when he latched onto a through ball from substitute Joshua Zirkzee and guided a shot underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when Amorim is without four 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.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impression, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The point extends Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points 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, wasted.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers 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 poor results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming signings, lacking in belief 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 United Breakdown: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of expected fervor, but the intimidating edge was not as evident as in previous fixtures.
The home fans were more concerned 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 isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for the opener.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now overseeing clear improvement.
The job is not completed yet but step by step, Leeds are getting closer to achieving their survival.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also entering their FA Cup journey with a home tie.
