At a Glance
- Dominic Calvert-Lewin watches a first-half header ricochet off the post.
- Brenden Aaronson fires the home side ahead with a well-placed finish in the second period.
- Cunha levels just three minutes afterwards.
- Leeds extend their best top-flight unbeaten run since 2001.
The Red Devils' poor run of form persisted at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-period attempt against the woodwork for the in-form hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
However, against opponents who had two days less to recover, the forward levelled three minutes later when he latched onto a pass from substitute Joshua Zirkzee and guided a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when the manager is without several key attacking players due to a mix of fitness issues and national team commitments.
Not that Leeds to care about that given their own lack of preparation time.
Noah Okafor 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 finding it hard to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The point extends Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team's options.
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 limited alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the hostile edge was not as evident as in other encounters.
The home fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The striker's header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for the opener.
For a short moment, Leeds' 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 Leeds to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's position.
Instead, he is now overseeing significant progress.
The job is not done yet but gradually, Leeds are getting closer to securing their survival.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
