Key Moments
- Calvert-Lewin watches a first-half header ricochet off the post.
- Aaronson fires the hosts ahead with a low effort in the second half.
- Matheus Cunha responds just three minutes afterwards.
- Leeds extend their longest Premier League unbeaten run since the turn of the century.
The Red Devils' poor 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 headed a first-half attempt against the woodwork for the in-form home team before the American midfielder finished superbly with a low, 62nd-minute shot.
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.
However, against opponents who had two days less to prepare, Cunha restored parity three minutes after the opener when he ran on to a pass from introduced the Dutchman and guided a finish underneath advancing 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 the manager is without several key attacking players due to a mix of injury and international duty.
Not that Leeds to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting 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 ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The point extends the home side's unbeaten run to seven matches, 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 chance to move into the Champions League places, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the participating nations make a pretty quick 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 Amorim's squad.
It's not that the missing pair are the answer to all of United'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 Dutch forward provided the assist for the equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and assurance 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 United Breakdown: A Further Step Towards Survival
After memorable victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were moments of typical fervor, but the intimidating edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's struggle to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were struggling when a defensive error opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a wider context for Daniel Farke 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.
Instead, he is now overseeing significant progress.
The job is not done yet but step by step, the team are getting nearer to achieving their top-flight status.
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. The Red Devils face a league trip to Turf Moor before also entering their FA Cup journey with a Old Trafford tie.
