Match Summary
- Dominic Calvert-Lewin sees a first-half header come back off the upright.
- Brenden Aaronson puts the home side ahead with a well-placed strike in the second half.
- Cunha levels only three minutes later.
- The Yorkshire side continue their best Premier League undefeated streak since the turn of the century.
The Red Devils' poor run of form persisted at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the post for the in-form home team before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against opponents who had less time to prepare, Cunha levelled three minutes later when he ran on to a pass from introduced Joshua Zirkzee and slid a finish underneath rushing Leeds 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 several key attacking players due to a mix of fitness issues and national team commitments.
Not that you would expect Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw extends Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, squandered.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood 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 absence of other forwards is having on the team'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 disappointing results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their natural 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.
Sesko's failure to turn home the 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 last few home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected fervor, but the intimidating edge was not as evident as in other fixtures.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were struggling when a defensive error opened the door for the opener.
For a short moment, The home delirious fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for the manager and the club to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now overseeing significant improvement.
The job is not completed yet but gradually, the team are getting closer to securing their top-flight status.
Looking Ahead
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their cup journey with a home tie.
