At a Glance
Manchester United's disappointing recent struggles continued at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more disappointment against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the post for the confident home team before Brenden Aaronson applied a cool finish with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had less time to recover, Cunha restored parity three minutes after the opener when he ran on to a pass from introduced Joshua Zirkzee and slid a shot underneath rushing 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 several key attacking players due to a mix of injury and international duty.
Not that you would expect the hosts to care about that given their own lack of preparation time.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, wasted.
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other attackers is having on the team'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 season.
But without them, Amorim has limited alternatives in attack.
He clearly does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands 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 natural positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
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 moments of expected atmosphere, but the hostile edge was not as pronounced as in other fixtures.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any length of time.
The Calvert-Lewin header that clipped the post was an isolated moment of quality in a congested first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a coveted 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 future.
Instead, he is now overseeing clear improvement.
The job is not done yet but gradually, Leeds are getting nearer to achieving their top-flight status.
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
