At a Glance
Manchester United's disappointing recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more disappointment against Leeds.
Dominic Calvert-Lewin directed a first-period effort against the woodwork for the confident home team before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had been held by struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha restored parity three minutes later when he latched onto a pass from introduced Joshua Zirkzee and guided a shot underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his big-money 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 care about that given their own lack of preparation time.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on the team's squad.
It's not that the missing pair are the answer to all of the club's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as evident as in other encounters.
The home fans were more preoccupied about their side's inability to get sustained possession in advanced areas for any prolonged period.
The striker's header that struck the post was an rare moment of threat in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' delirious 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 endured a poor run of form earlier in the season, many thought about the manager's position.
Instead, he is now masterminding significant improvement.
The task is not done yet but step by step, Leeds are getting nearer to achieving their top-flight status.
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their cup journey with a home tie.
