Match Summary
- Dominic Calvert-Lewin watches a early header come back off the post.
- Aaronson fires the hosts ahead with a well-placed finish in the second half.
- Cunha responds just three minutes later.
- Leeds continue their best Premier League undefeated streak since 2001.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-period attempt against the post for the in-form home team before Brenden Aaronson applied a cool finish with a driven, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against a team who had two days less to prepare, Cunha levelled three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and guided a shot underneath rushing Leeds 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 four key attacking players due to a mix of fitness issues and international duty.
Not that the hosts to care about that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting 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 Zirkzee's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The point extends Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other forwards is having on Amorim's squad.
It's not that the missing pair are the answer to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, the boss has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their last few home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as evident as in previous encounters.
The home fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The striker's header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' delirious 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 poor run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now masterminding significant progress.
The task is not done yet but step by step, the team are getting nearer to securing their top-flight status.
Looking Ahead
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Turf Moor before also entering their cup journey with a home tie.
