Key Moments
- Calvert-Lewin watches a early header ricochet off the upright.
- Brenden Aaronson fires the home side ahead with a low effort in the second period.
- Matheus Cunha responds just three minutes later.
- The Yorkshire side continue their best top-flight unbeaten run since 2001.
The Red Devils' disappointing run of form continued at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more disappointment against Leeds.
The Everton loanee headed a first-period attempt against the post for the in-form hosts before the American midfielder finished superbly with a low, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had less time to recover, the forward levelled three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and guided a finish underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a mix of fitness issues and national team commitments.
Not that the hosts to care about that given their own lack of preparation time.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling 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 match, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's squad.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that experienced poor results earlier in the season.
But without them, Amorim has few attacking options.
He evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous struggling signings, lacking in belief 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 young striker.
Leeds United Breakdown: A Further Step Towards Survival
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 fervor, but the intimidating edge was not as evident as in previous fixtures.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The striker's header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a rare 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 thought about the manager's future.
In contrast, he is now masterminding significant progress.
The task is not completed yet but gradually, the team are getting nearer to achieving their top-flight status.
Looking Ahead
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
