Key Moments
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson fires the hosts ahead with a low strike in the second half.
- Matheus Cunha levels just three minutes afterwards.
- Leeds continue their best top-flight unbeaten run since the turn of the century.
The Red Devils' poor run of form continued at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against their old rivals.
The Everton loanee directed a first-period attempt against the post for the confident hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha restored parity three minutes after the opener when he ran on to a through ball from substitute Joshua Zirkzee and guided a shot underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian'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 combination of injury and national team commitments.
Not that you would expect the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The point extends Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a short time, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other forwards is having on Amorim's squad.
It's not that the absent players are the answer to all of United'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 evidently does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for the equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in confidence and assurance 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.
Leeds Analysis: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as evident as in previous encounters.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin header that struck 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 defensive error opened the door for Aaronson.
For a short moment, The home delirious fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for Daniel Farke 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 significant progress.
The job is not completed yet but step by step, the team are getting nearer to achieving their survival.
Looking Ahead
Leeds have a top-flight 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 home tie.
