Key Moments
- Calvert-Lewin sees a first-half header come back off the upright.
- Brenden Aaronson puts the home side ahead with a well-placed effort in the second half.
- Cunha responds only three minutes later.
- Leeds extend their longest top-flight unbeaten run since the turn of the century.
Manchester United's poor run of form continued at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
However, against opponents who had two days less to recover, the forward restored parity three minutes later when he ran on to a pass from introduced the Dutchman and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American'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 fitness issues and national team commitments.
Not that Leeds to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven games, their best 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 short time, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other attackers is having on Amorim's options.
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 experienced poor results earlier in the campaign.
But without them, Amorim has few attacking options.
He clearly does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost immediately after his arrival as a substitute.
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 similar to previous underwhelming signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Survival
After memorable victories in their previous home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the hostile edge was not as pronounced 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 striker's header that struck 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.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
However, 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.
In contrast, he is now overseeing clear progress.
The job is not completed yet but step by step, Leeds are getting nearer to achieving their survival.
What Happens Next?
