Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Brenden Aaronson puts the home side ahead with a well-placed effort in the second half.
- Cunha responds just three minutes later.
- Leeds extend their longest top-flight unbeaten run since 2001.
Manchester United's poor run of form continued at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more disappointment against their old rivals.
The Everton loanee headed a first-period effort against the woodwork for the in-form hosts before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat struggling Wolves at home earlier in the week.
However, against opponents who had two days less to prepare, the forward restored parity three minutes later when he ran on to a pass from introduced Joshua Zirkzee and slid a finish underneath rushing Leeds 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 mix of injury and national team commitments.
Not that Leeds to care about that given their own lack of preparation time.
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 the Slovenian striker, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The draw prolongs 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 fourth spot, albeit only for a matter of hours, squandered.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team's squad.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, the boss has limited alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the assist 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 operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to 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: Another Step Towards Survival
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 moments of typical fervor, but the hostile edge was not as pronounced as in previous encounters.
Leeds' fans were more concerned about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of threat in a tight first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the campaign, many thought about the manager's position.
Instead, he is now masterminding clear progress.
The job is not completed yet but step by step, Leeds are getting nearer to achieving their survival.
