At a Glance
- Dominic Calvert-Lewin watches a early header ricochet off the post.
- Brenden Aaronson fires the home side ahead with a low effort in the second period.
- Cunha responds only three minutes later.
- Leeds extend their longest Premier League undefeated streak since 2001.
The Red Devils' poor run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
With the goal, the United boss 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 a team who had two days less to recover, Cunha restored parity three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League 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 international duty.
Not that you would expect the hosts 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 spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impression, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The point extends Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, and takes them eight points 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, 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 captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers is having on the team's options.
It's not that the absent players are the answer to all of the club's problems. After all, they were part of the side that suffered poor results earlier in the season.
But without them, Amorim has limited 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 arrival as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Sesko.
On this evidence, the expensive frontman looks no better than previous struggling signings, lacking in belief and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Survival
After memorable victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of expected fervor, but the hostile edge was not as pronounced as in other encounters.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an rare moment of quality in a tight first half.
It still felt as though Leeds were struggling when a defensive error opened the door for the opener.
For a short moment, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
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 position.
Instead, he is now overseeing significant improvement.
The task is not done yet but step by step, the team are getting closer to securing their survival.
Looking Ahead
The Yorkshire club 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 Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
