Key Moments
- Dominic Calvert-Lewin sees a first-half header come back off the upright.
- Brenden Aaronson fires the hosts ahead with a well-placed effort in the second half.
- Matheus Cunha responds only three minutes later.
- Leeds continue their longest top-flight unbeaten run since the turn of the century.
Manchester United's poor recent struggles persisted at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the in-form home team before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to prepare, the forward restored parity three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and slid a finish underneath advancing 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 several key attacking players due to a combination of injury and international duty.
Not that the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United 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 impression, turned his teammate's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also blasted against a post in the dying moments.
The draw prolongs the home side's 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 opportunity to move into the Champions League places, albeit only for a matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be forgiven 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 attackers is having on the team's options.
It's not that the absent players are the answer 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 limited attacking options.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the assist 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 Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Survival
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a bit drab 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 worthwhile possession in dangerous areas for any prolonged period.
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 finding it tough when a defensive error opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now overseeing significant progress.
The task is not done yet but step by step, Leeds are getting closer to achieving their top-flight status.
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 Premier League trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
