At a Glance
- Calvert-Lewin sees a early header ricochet off the post.
- Brenden Aaronson puts the hosts ahead with a well-placed finish in the second half.
- Cunha responds just three minutes later.
- Leeds extend their longest Premier League unbeaten run since 2001.
The Red Devils' poor run of form persisted at Elland Road, but head coach the Portuguese tactician had Matheus Cunha to thank for the team not suffering even more disappointment against their old rivals.
The Everton loanee directed a first-half attempt against the post for the confident hosts before Brenden Aaronson finished superbly with a driven, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against opponents who had less time to recover, Cunha levelled three minutes later when he ran on to a through ball from introduced the Dutchman and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian'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 injury and international duty.
Not that the hosts to sympathise with that given their own lack of preparation time.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard 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 blasted against a post late on.
The point extends Leeds' unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
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 participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other attackers is having on Amorim'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 campaign.
But without them, the boss has limited attacking options.
He clearly does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in belief 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 young striker.
Leeds Analysis: Another Step Towards Safety
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 instances of typical fervor, but the hostile edge was not as evident as in previous fixtures.
The home fans were more concerned about their side's inability to get sustained possession in dangerous areas for any length of time.
The striker's header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager 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.
Instead, he is now masterminding clear improvement.
The job is not done yet but gradually, the team are getting nearer to achieving their top-flight status.
What Happens Next?
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also entering their cup journey with a Old Trafford tie.
