Key Moments
- Calvert-Lewin sees a early header ricochet off the upright.
- Brenden Aaronson fires the hosts ahead with a low finish in the second period.
- Cunha levels just three minutes afterwards.
- The Yorkshire side continue their longest Premier League undefeated streak since 2001.
The Red Devils' disappointing recent struggles persisted at Elland Road, but head coach the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the confident home team before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had two days less to prepare, the forward restored parity three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian'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 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 audacious overhead kick, and United 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.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The point extends the home side's unbeaten run to seven games, their best such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, the United coach could be forgiven for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability 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 experienced poor results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now nine games 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 fiercest rivals to home was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as pronounced as in previous encounters.
The home fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an rare moment of quality in a tight first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for the opener.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a much bigger picture for Daniel Farke and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now overseeing significant improvement.
The job is not done yet but gradually, Leeds 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 domestic cup campaign next weekend. The Red Devils face a league trip to Burnley before also beginning their FA Cup journey with a home tie.
