Key Moments
- Calvert-Lewin sees a early header come back off the post.
- Aaronson fires the hosts ahead with a low strike in the second period.
- Cunha responds just three minutes later.
- The Yorkshire side continue their longest Premier League unbeaten run since 2001.
Manchester United's 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 their old rivals.
The Everton loanee headed a first-half effort against the woodwork for the in-form hosts before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had less time to prepare, Cunha restored parity three minutes after the opener when he ran on to a through ball from introduced Joshua Zirkzee and guided 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 Amorim is without four key attacking players due to a combination of injury and national team commitments.
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 audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
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 longest such streak since 2001, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: The Manager'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 captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers 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 suffered disappointing results earlier in the campaign.
But without them, the boss has few attacking options.
He clearly does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of expected fervor, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more preoccupied about their side's inability to get worthwhile possession in advanced areas for any length of time.
The striker's header that struck the post was an isolated moment of quality 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' ecstatic fans thought they were about to secure a coveted win against their old foes.
However, there is a wider context for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now masterminding significant progress.
The job is not completed yet but gradually, Leeds are getting nearer to achieving their top-flight status.
What Happens Next?
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a Premier League trip to Turf Moor before also beginning their cup journey with a Old Trafford tie.
