Key Moments
- Dominic Calvert-Lewin watches a early header ricochet off the upright.
- Brenden Aaronson fires the home side ahead with a well-placed finish in the second half.
- Cunha responds just three minutes afterwards.
- The Yorkshire side continue their longest Premier League unbeaten run since 2001.
The Red Devils' disappointing run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more disappointment against their old rivals.
The Everton loanee headed a first-half attempt against the woodwork for the in-form home team before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
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.
However, against opponents who had less time to prepare, Cunha levelled three minutes later when he latched onto a through ball from introduced Joshua Zirkzee and slid a shot underneath rushing home goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without several key attacking players due to a mix of fitness issues and international duty.
Not that 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 the Slovenian striker, who is struggling to make an impact, turned his teammate'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 longest such streak since 2001, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on Amorim'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 alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the assist for Cunha's equaliser almost immediately after his arrival as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
His 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 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 intimidating edge was not as evident as in previous fixtures.
Leeds' fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of threat 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, The home ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for the manager and the club to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now overseeing clear improvement.
The task is not done yet but step by step, the team are getting closer to securing their top-flight status.
What Happens Next?
The Yorkshire club have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also entering their FA Cup journey with a home tie.
