Match Summary
- Dominic Calvert-Lewin watches a early header ricochet off the post.
- Brenden Aaronson puts the home side ahead with a well-placed effort in the second period.
- Cunha levels only three minutes later.
- The Yorkshire side extend their best Premier League unbeaten run since the turn of the century.
The Red Devils' disappointing run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more disappointment against their old rivals.
The Everton loanee headed a first-half effort against the woodwork for the in-form hosts before the American midfielder finished superbly with a low, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had less time to prepare, the forward levelled three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a mix of fitness issues and national team commitments.
Not that you would expect the hosts to care about that given their own tight schedule.
Noah Okafor 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 finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's squad.
It's not that the absent players 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 season.
But without them, Amorim has limited alternatives in attack.
He evidently does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After memorable victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as pronounced as in previous fixtures.
Leeds' fans were more preoccupied about their side's inability to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
For a short moment, The home delirious fans thought they were about to secure a rare win against Manchester United.
However, there is a much bigger picture for Daniel Farke and the club to deal with.
When they endured a poor run of form earlier in the campaign, many speculated about the manager's future.
In contrast, he is now masterminding clear progress.
The job is not done yet but gradually, Leeds are getting closer to securing their top-flight status.
What Happens Next?
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 Premier League trip to Turf Moor before also entering their cup journey with a Old Trafford tie.
