Match Summary
Manchester United's poor recent struggles persisted at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for the team not suffering even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the woodwork for the in-form hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
Nevertheless, against opponents who had two days less to recover, the forward restored parity three minutes later when he ran on to a through ball from introduced Joshua Zirkzee and guided a finish underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when the manager is without several key attacking players due to a combination of injury 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 audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The draw extends Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United 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 latter stages, the United coach could be forgiven for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on Amorim's squad.
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 poor results earlier in the campaign.
But without them, Amorim has limited attacking options.
He evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to 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 young striker.
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as evident as in other fixtures.
The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of threat in a tight first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for the opener.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a wider context for Daniel Farke and the club to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's future.
In contrast, he is now overseeing clear improvement.
The job is not done yet but gradually, the team are getting closer to achieving their top-flight status.
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
