At a Glance
- Calvert-Lewin sees a first-half header come back off the post.
- Aaronson puts the hosts ahead with a well-placed finish in the second half.
- Matheus Cunha levels only three minutes later.
- Leeds continue their longest top-flight unbeaten run since 2001.
Manchester United's disappointing run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against Leeds.
Dominic Calvert-Lewin directed a first-half effort against the woodwork for the confident home team before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had been held by struggling Wolves at Old Trafford earlier in the week.
However, against a team who had less time to prepare, Cunha levelled three minutes after the opener when he latched onto a pass from substitute Joshua Zirkzee and guided a finish underneath rushing home 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 the manager is without four 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.
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 the Slovenian striker, who is finding it hard to make an impression, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven matches, their longest such streak since over two decades ago, 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, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on the team's options.
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 poor results earlier in the campaign.
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 Joshua Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in belief and conviction 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 Survival
After memorable victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the hostile edge was not as pronounced as in previous encounters.
Leeds' fans were more preoccupied about their side's inability to get worthwhile possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that struck 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' ecstatic fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for the manager and the club to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's future.
Instead, he is now masterminding significant improvement.
The task is not completed yet but step by step, Leeds are getting closer to achieving their survival.
Looking Ahead
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 league trip to Turf Moor before also beginning their cup journey with a Old Trafford tie.
