Match Summary
- Dominic Calvert-Lewin watches a early header ricochet off the upright.
- Brenden Aaronson fires the home side ahead with a well-placed strike in the second half.
- Matheus Cunha levels just three minutes later.
- The Yorkshire side extend their longest top-flight undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more damage against their old rivals.
The Everton loanee headed a first-half attempt against the woodwork for the confident home team before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to prepare, the forward restored parity three minutes after the opener when he ran on to a through ball from introduced the Dutchman and guided a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a combination 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 diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned Zirkzee'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 late on.
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 visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
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 involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other forwards is having on the team'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 experienced poor results earlier in the season.
But without them, Amorim has few alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds Analysis: Another Step Towards Safety
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more concerned about their side's inability to get sustained possession in advanced areas for any prolonged period.
The striker's header that struck the post was an rare 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 ecstatic fans thought they were about to secure a rare win against Manchester United.
However, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now overseeing significant progress.
The task is not completed yet but step by step, the team are getting closer to securing their survival.
Looking Ahead
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their cup journey with a Old Trafford tie.
