Match Summary
- Calvert-Lewin sees a early header come back off the post.
- Brenden Aaronson puts the hosts ahead with a well-placed effort in the second half.
- Matheus Cunha responds just three minutes later.
- The Yorkshire side extend their best Premier League undefeated streak since 2001.
Manchester United's poor run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
The Everton loanee directed a first-half attempt against the woodwork for the in-form hosts before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to recover, Cunha restored parity three minutes later when he ran on to a pass from introduced the Dutchman and guided a finish underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a combination of injury and international duty.
Not that you would expect Leeds to care about that given their own lack of preparation time.
Noah Okafor 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 disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw extends the home side's unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another chance 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 knockout phase, the United coach could be understood for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team'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 experienced poor results earlier in the campaign.
But without them, Amorim has limited attacking options.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous struggling signings, lacking in confidence 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 new signing.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the hostile edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin header that clipped the post was an isolated 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 Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now masterminding significant progress.
The task is not completed yet but gradually, the team are getting nearer to securing their top-flight status.
Looking Ahead
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Turf Moor before also entering their FA Cup journey with a home tie.
