Key Moments
- Dominic Calvert-Lewin watches a first-half header come back off the post.
- Aaronson fires the hosts ahead with a low finish in the second half.
- Cunha equalises only three minutes later.
- Leeds extend their best top-flight undefeated streak since 2001.
The Red Devils' poor recent struggles continued at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against Leeds.
The Everton loanee directed a first-period attempt against the post for the in-form 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 failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had two days less to recover, the forward levelled three minutes after the opener when he ran on to a pass from substitute the Dutchman and slid a finish underneath rushing home goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without several key attacking players due to a combination of injury and international duty.
Not that Leeds to care about that given their own lack of preparation time.
The Swiss attacker forced a diving 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 his teammate's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The point extends the home side's unbeaten run to seven games, their longest such streak since 2001, 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 matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards 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 experienced disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his arrival 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 big-money frontman looks similar to 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 United Breakdown: A Further 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.
The home fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a congested 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' ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now masterminding clear progress.
The task is not completed yet but gradually, Leeds are getting nearer to securing their top-flight status.
What Happens Next?
The Yorkshire club 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 beginning their cup journey with a home tie.
