Key Moments
- Calvert-Lewin sees a first-half header come back off the post.
- Aaronson puts the home side ahead with a well-placed effort in the second period.
- Cunha responds just three minutes later.
- Leeds extend their longest Premier League unbeaten run since the turn of the century.
Manchester United's poor run of form persisted at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin directed a first-period attempt against the post for the confident hosts before the American midfielder applied a cool finish with a low, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
However, against opponents who had two days less to recover, Cunha restored parity three minutes later when he latched onto a pass from substitute the Dutchman and guided a shot underneath advancing Leeds 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 Amorim is without several key attacking players due to a combination of injury and international duty.
Not that you would expect Leeds to care about that given their own lack of preparation time.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from close range.
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 extends Leeds' 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, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim'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 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 three goals in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in confidence and conviction in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Survival
After memorable victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of typical fervor, but the intimidating edge was not as pronounced as in other fixtures.
Leeds' fans were more concerned about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The striker's header that clipped the post was an rare moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's position.
In contrast, he is now overseeing clear improvement.
The task is not completed yet but gradually, Leeds are getting closer to securing their survival.
Looking Ahead
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their FA Cup journey with a home tie.
