Key Moments
- Calvert-Lewin sees a early header ricochet off the upright.
- Brenden Aaronson fires the hosts ahead with a well-placed effort in the second half.
- Cunha levels only three minutes later.
- Leeds extend their longest top-flight unbeaten run since 2001.
The Red Devils' disappointing run of form persisted at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more disappointment against their old rivals.
The Everton loanee headed a first-period attempt against the woodwork for the confident home team before the American midfielder finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha levelled three minutes later when he ran on to a pass from substitute the Dutchman and slid a finish underneath advancing Leeds 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 combination of injury and national team commitments.
Not that the hosts to care about that given their own lack of preparation time.
Noah Okafor forced a full length 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 impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The point extends Leeds' unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the relegation 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, wasted.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the participating nations make a swift exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other attackers 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 suffered disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost immediately after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their preferred 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.
His failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds Analysis: Another Step Towards Survival
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 typical fervor, but the intimidating edge was not as evident as in previous fixtures.
Leeds' fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The striker's header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for the opener.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for Daniel Farke and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's future.
In contrast, he is now masterminding significant progress.
The task is not completed yet but step by step, the team are getting closer to securing their survival.
What Happens Next?
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 Burnley before also entering their FA Cup journey with a Old Trafford tie.
