Match Summary
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Aaronson fires the home side ahead with a well-placed strike in the second half.
- Matheus Cunha levels only three minutes afterwards.
- Leeds extend their best top-flight undefeated streak since the turn of the century.
Manchester United's disappointing run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
The Everton loanee headed a first-period effort against the post for the confident home team before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had two days less to prepare, 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 Leeds 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 Amorim is without four key attacking players due to a mix of fitness issues and international duty.
Not that the hosts 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 spectacular 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.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The draw extends Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's squad.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that experienced poor results earlier in the season.
But without them, Amorim has limited attacking options.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of expected fervor, but the hostile edge was not as evident as in other encounters.
The home fans were more concerned about their side's inability to get worthwhile possession in dangerous areas for any length of time.
The striker's header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for the opener.
For a short moment, The home delirious 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 suffered a difficult run of form earlier in the campaign, many speculated about the manager's future.
In contrast, he is now masterminding clear progress.
The job is not done yet but gradually, Leeds are getting nearer to securing their top-flight status.
