At a Glance
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Brenden Aaronson fires the hosts ahead with a well-placed strike in the second period.
- Matheus Cunha responds only three minutes later.
- Leeds continue their best Premier League unbeaten run since 2001.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post for the in-form home team before Brenden Aaronson applied a cool finish with a driven, 62nd-minute effort.
At that stage, 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 prepare, Cunha restored parity three minutes later when he ran on to a pass from introduced Joshua Zirkzee and guided a finish 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 the manager is without four key attacking players due to a mix of injury 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 United heads were in hands when the Slovenian striker, who is struggling to make an impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to captain 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 solution to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks no better than previous struggling signings, lacking in belief and assurance 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 Analysis: Another Step Towards Survival
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of expected fervor, but the intimidating edge was not as pronounced as in previous fixtures.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an isolated moment of threat in a tight first half.
It still felt as though the hosts were struggling when a defensive error opened the door for the opener.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
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 clear improvement.
The task is not completed yet but gradually, Leeds are getting closer to achieving their top-flight status.
Looking Ahead
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also entering their FA Cup journey with a home tie.
