Key Moments
- Calvert-Lewin watches a early header ricochet off the upright.
- Brenden Aaronson puts the home side ahead with a well-placed strike in the second period.
- Cunha equalises only three minutes afterwards.
- Leeds extend their longest Premier League unbeaten run since the turn of the century.
The Red Devils' poor run of form persisted at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-period attempt against the post for the in-form hosts before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had failed to beat struggling Wolves at home earlier in the week.
However, against opponents who had two days less to recover, the forward restored parity three minutes later when he ran on to a pass from introduced the Dutchman and guided a finish underneath rushing home 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 several key attacking players due to a combination of fitness issues and national team commitments.
Not that you would expect the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of visiting 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 impact, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw extends Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, wasted.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team's options.
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 campaign.
But without them, Amorim has limited alternatives in attack.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, 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 nine games without a goal for the new signing.
Leeds Analysis: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of expected fervor, but the hostile edge was not as pronounced as in other encounters.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in advanced 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 struggling when a mistake opened the door for the opener.
Ever so briefly, 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 the club to deal with.
When they endured a difficult run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now masterminding clear improvement.
The task is not done yet but gradually, Leeds are getting closer to securing their top-flight status.
Looking Ahead
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. Manchester United face a league trip to Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
