Key Moments
- Calvert-Lewin sees a first-half header come back off the post.
- Aaronson puts the hosts ahead with a well-placed strike in the second period.
- Cunha equalises just three minutes afterwards.
- The Yorkshire side continue their best Premier League unbeaten run since 2001.
The Red Devils' disappointing recent struggles continued at Elland Road, but manager the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more disappointment against their old rivals.
The Everton loanee headed a first-half attempt against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against opponents who had less time to prepare, Cunha levelled three minutes after the opener when he ran on to a pass from introduced Joshua Zirkzee and slid a shot underneath rushing Leeds 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 Amorim is without several key attacking players due to a combination of injury and national team commitments.
Not that Leeds to sympathise with 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 finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw extends the home side's unbeaten run to seven matches, their longest such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a swift exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other attackers 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 experienced disappointing results earlier in the season.
But without them, Amorim has few attacking options.
He clearly does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in confidence and assurance 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 Survival
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 typical fervor, but the hostile edge was not as pronounced as in previous fixtures.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
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 mistake opened the door for the opener.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now overseeing significant progress.
The task is not completed yet but step by step, Leeds are getting closer to achieving their survival.
What Happens Next?
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
