Match Summary
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson puts the home side ahead with a well-placed strike in the second half.
- Cunha levels only three minutes afterwards.
- The Yorkshire side continue their best top-flight undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for the team not suffering even more damage against their old rivals.
The Everton loanee directed a first-half attempt against the post for the confident hosts before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had been held by struggling Wolves at home earlier in the week.
However, against opponents who had two days less to prepare, the forward levelled three minutes later when he latched onto a pass from substitute Joshua Zirkzee 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 combination of fitness issues and national team commitments.
Not that you would expect Leeds to care about that given their own tight schedule.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a audacious 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.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw prolongs Leeds' unbeaten run to seven games, their longest such streak since 2001, 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 AFCON reaching its knockout phase, Amorim could be understood for hoping the involved countries make a swift exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on Amorim's squad.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost immediately after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as evident as in previous fixtures.
The home fans were more concerned about their side's inability to get sustained possession in advanced areas for any prolonged period.
The striker's header that struck the post was an rare moment of quality in a congested first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for the opener.
For a short moment, The home ecstatic 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 endured a poor run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now masterminding clear progress.
The task is not done yet but gradually, Leeds are getting closer to achieving their survival.
What Happens Next?
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also entering their FA Cup journey with a home tie.
