At a Glance
Manchester United's disappointing recent struggles persisted at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more disappointment against Leeds.
The Everton loanee headed a first-half attempt against the woodwork for the in-form hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against opponents who had less time to prepare, Cunha levelled three minutes later when he ran on to a through ball from introduced Joshua Zirkzee and guided a shot underneath advancing home goalkeeper Lucas Perri.
It was only the South American'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 Leeds to care about that given their own tight schedule.
Noah Okafor forced a full length save out of visiting 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.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also blasted against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them eight points clear of the drop 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.
With the AFCON reaching its latter stages, Amorim could be understood for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other forwards is having on the team's squad.
It's not that the missing pair are the answer to all of United's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, Amorim has few attacking options.
He evidently does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the young striker.
After memorable victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were instances of expected fervor, but the intimidating 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 prolonged period.
The striker's header that clipped the post was an isolated moment of threat in a tight first half.
It still felt as though the hosts were struggling 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 Manchester United.
However, there is a wider context for Daniel Farke and the club to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's future.
In contrast, he is now masterminding clear improvement.
The job is not completed yet but gradually, Leeds are getting closer to securing their survival.
The Yorkshire club have a Premier League trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also entering their FA Cup journey with a home tie.
