Key Moments
- Dominic Calvert-Lewin watches a first-half header come back off the post.
- Brenden Aaronson fires the home side ahead with a well-placed finish in the second period.
- Matheus Cunha equalises only three minutes afterwards.
- Leeds continue their longest Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more damage 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.
With the goal, Amorim was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha levelled three minutes later when he ran on to a pass from introduced the Dutchman and guided a shot 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 several key attacking players due to a mix of injury and international duty.
Not that 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 audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling 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 blasted against a post in the dying moments.
The draw extends Leeds' unbeaten run to seven games, their longest 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 matter of hours, wasted.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on Amorim's options.
It's not that the missing pair are the answer 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 few attacking options.
He evidently does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in belief 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: A Further Step Towards Safety
After thrilling 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 typical fervor, but the hostile edge was not as pronounced as in previous fixtures.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were finding it tough when a mistake 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 Daniel Farke and the club to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's position.
Instead, he is now overseeing clear improvement.
The job is not done yet but gradually, Leeds are getting nearer to securing their top-flight status.
What Happens Next?
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also entering their FA Cup journey with a home tie.
