Match Summary
- Calvert-Lewin watches a early header come back off the upright.
- Brenden Aaronson puts the hosts ahead with a well-placed finish in the second half.
- Matheus Cunha equalises just three minutes afterwards.
- Leeds extend their best top-flight undefeated streak since 2001.
The Red Devils' poor run of form persisted at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-period attempt against the post for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against a team who had two days less to prepare, the forward levelled three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and slid a shot 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 four key attacking players due to a combination of injury and international duty.
Not that Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired against a post in the dying moments.
The point prolongs Leeds' 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 Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on the team's squad.
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 suffered poor results earlier in the campaign.
But without them, the boss has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks no better than previous struggling 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 young striker.
Leeds United Breakdown: A Further Step Towards Survival
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 instances of expected atmosphere, but the hostile edge was not as evident as in previous encounters.
The home fans were more concerned about their side's inability to get sustained possession in advanced areas for any length of time.
The striker's header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds 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 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.
In contrast, he is now overseeing significant progress.
The task is not done yet but step by step, Leeds are getting nearer to achieving their top-flight status.
Looking Ahead
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their FA Cup journey with a home tie.
