Key Moments
- Dominic Calvert-Lewin sees a early header come back off the upright.
- Aaronson puts the hosts ahead with a well-placed effort in the second period.
- Cunha responds just three minutes later.
- Leeds extend their longest top-flight undefeated streak since the turn of the century.
Manchester United's poor recent struggles continued at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more disappointment against Leeds.
Dominic Calvert-Lewin directed a first-half attempt against the post for the in-form home team before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
At that stage, 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 less time to recover, Cunha levelled three minutes later when he latched onto a through ball from introduced Joshua Zirkzee and slid a finish underneath rushing 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 mix of fitness issues and national team commitments.
Not that you would expect Leeds to sympathise with that given their own tight schedule.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The draw prolongs Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, squandered.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be forgiven for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international 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 solution 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 alternatives in attack.
He clearly does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating 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 Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds Analysis: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were instances of expected atmosphere, but the intimidating edge was not as pronounced as in other fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an rare moment of threat in a tight first half.
It still felt as though the hosts were finding it tough when a mistake 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 endured a difficult run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now overseeing clear progress.
The job is not done yet but gradually, the team are getting nearer to securing their survival.
Looking Ahead
The Yorkshire club 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 Premier League trip to Burnley before also entering their cup journey with a Old Trafford tie.
