Manchester United's poor recent struggles continued at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more disappointment against Leeds.
The Everton loanee directed a first-period effort against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had less time to prepare, Cunha levelled three minutes later when he ran on to a pass from introduced Joshua Zirkzee and slid a finish underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian'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 combination of fitness issues and international duty.
Not that the hosts to sympathise with 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 struggling to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw prolongs the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin 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 matter of hours, squandered.
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other attackers 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 experienced disappointing results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous struggling 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.
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as evident as in other encounters.
The home fans were more preoccupied about their side's inability to get worthwhile possession in dangerous areas for any length of time.
The striker's 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.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now overseeing clear progress.
The task is not completed yet but gradually, the team are getting closer to securing their top-flight status.
Leeds have a Premier League 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 beginning their cup journey with a Old Trafford tie.
