Match Summary
Manchester United's poor run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more disappointment against Leeds.
Dominic Calvert-Lewin headed a first-half effort against the woodwork for the in-form home team before the American midfielder 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 Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to recover, Cunha restored parity three minutes after the opener when he latched onto a pass from substitute Joshua Zirkzee and guided a shot underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a mix of fitness issues and national team commitments.
Not that the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting 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.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The point 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.
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other attackers is having on Amorim'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 poor results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He evidently does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming 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 new signing.
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of expected fervor, but the intimidating edge was not as evident as in previous encounters.
Leeds' fans were more concerned about their side's struggle to get sustained possession in dangerous areas for any length of time.
The striker's header that struck 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 mistake opened the door for Aaronson.
For a short moment, The home ecstatic fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now masterminding significant progress.
The job is not completed yet but step by step, the team are getting nearer to achieving their top-flight status.
The Yorkshire club 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.
