Key Moments
- Calvert-Lewin sees a early header come back off the upright.
- Brenden Aaronson fires the home side ahead with a low strike in the second half.
- Cunha levels just three minutes afterwards.
- The Yorkshire side continue their longest top-flight undefeated streak since 2001.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more damage against Leeds.
The Everton loanee directed a first-half effort against the post for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute shot.
At that stage, Amorim was in the firing line 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 prepare, Cunha levelled three minutes later when he latched onto a through ball from introduced 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 the manager is without several key attacking players due to a mix of injury and national team commitments.
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 audacious 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 six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The point extends Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the participating nations make a swift exit.
Current injuries to skipper 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 absent players are the answer 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, 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 Dutch forward delivered the through ball for the equaliser almost instantly after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in belief and assurance 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 thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the hostile edge was not as evident as in previous fixtures.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were struggling when a defensive error opened the door for the opener.
For a short moment, Leeds' delirious 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 endured a poor run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now masterminding significant progress.
The job is not done yet but step by step, Leeds are getting closer to securing their survival.
What Happens Next?
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their cup journey with a Old Trafford tie.
