Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson fires the home side ahead with a well-placed effort in the second half.
- Matheus Cunha responds just three minutes afterwards.
- Leeds continue their longest top-flight unbeaten run 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.
Dominic Calvert-Lewin directed 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 under intense scrutiny after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
However, against a team who had two days less to recover, the forward restored parity three minutes later when he ran on to a pass from introduced Joshua Zirkzee and slid a finish underneath advancing Leeds 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 combination of fitness issues and international duty.
Not that you would expect Leeds to care about that given their own lack of preparation time.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impression, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post late on.
The point prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be forgiven for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's squad.
It's not that the missing pair are the solution to all of the club's problems. After all, they were part of the side that suffered poor results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Survival
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 expected fervor, but the intimidating edge was not as evident as in previous fixtures.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now masterminding clear improvement.
The job is not completed yet but gradually, Leeds are getting nearer to securing their survival.
Looking Ahead
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 Premier League trip to Turf Moor before also beginning their cup journey with a Old Trafford tie.
