Key Moments
- Dominic Calvert-Lewin watches a early header ricochet off the upright.
- Brenden Aaronson puts the home side ahead with a well-placed effort in the second period.
- Cunha responds only three minutes later.
- Leeds extend their longest top-flight unbeaten run since the turn of the century.
Manchester United's poor run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
The Everton loanee headed a first-half attempt against the woodwork for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had two days less to prepare, Cunha restored parity three minutes later when he latched onto a pass from introduced the Dutchman 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 several key attacking players due to a mix of fitness issues and international duty.
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 Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the match, also blasted against a post late on.
The point prolongs Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, 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.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on the team's squad.
It's not that the missing pair are the solution to all of United'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 much more experienced Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their last few 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 evident as in other encounters.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any length of time.
The striker's header that struck the post was an isolated moment of quality 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.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a much bigger picture for Daniel Farke and the club to deal with.
When they endured a poor run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now overseeing clear progress.
The task is not done yet but step by step, the team are getting nearer to achieving 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. The Red Devils face a Premier League trip to Turf Moor before also beginning their cup journey with a home tie.
