At a Glance
The Red Devils' disappointing recent struggles persisted at Elland Road, but manager the Portuguese tactician had Matheus Cunha to thank for the team not suffering even more damage against Leeds.
Dominic Calvert-Lewin headed a first-half attempt against the woodwork for the confident home team before the American midfielder applied a cool finish with a low, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against opponents who had less time to recover, the forward levelled three minutes after the opener when he latched onto a through ball from introduced the Dutchman and guided a shot underneath rushing 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 Amorim is without four key attacking players due to a mix of fitness issues and international duty.
Not that you would expect Leeds to care about 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 visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw prolongs Leeds' 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 short time, squandered.
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other attackers is having on the team's options.
It's not that the missing pair are the answer to all of United's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, the boss has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost instantly after his arrival as a replacement.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
After thrilling 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 atmosphere, but the intimidating 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 striker's header that clipped the post was an rare moment of quality in a tight first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a wider context for Daniel Farke and Leeds to deal with.
When they endured a poor run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now overseeing significant improvement.
The task is not done yet but gradually, Leeds are getting closer to achieving their top-flight status.
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also entering their FA Cup journey with a Old Trafford tie.
