Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson puts the home side ahead with a well-placed finish in the second period.
- Cunha levels just three minutes afterwards.
- The Yorkshire side continue their best Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing run of form persisted 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 effort against the post for the confident hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against a team who had less time to prepare, Cunha levelled three minutes after the opener when he ran on to a pass from substitute the Dutchman and slid a finish underneath rushing 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 four key attacking players due to a combination of fitness issues and international duty.
Not that Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also blasted against a post late on.
The point prolongs the home side's unbeaten run to seven games, their best such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, wasted.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its latter stages, Amorim could be forgiven for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other attackers is having on Amorim'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 poor results earlier in the campaign.
But without them, the boss has few attacking options.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of expected fervor, but the hostile edge was not as pronounced as in previous fixtures.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any length of time.
The Calvert-Lewin header that struck the post was an rare moment of quality in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
However, there is a wider context for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many speculated about the manager's position.
In contrast, he is now masterminding clear progress.
The task is not completed yet but step by step, Leeds are getting nearer to securing their survival.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
