At a Glance
- Dominic Calvert-Lewin sees a first-half header ricochet off the post.
- Brenden Aaronson fires the home side ahead with a low strike in the second period.
- Cunha levels just three minutes later.
- The Yorkshire side continue their longest Premier League undefeated streak since 2001.
The Red Devils' disappointing recent struggles continued at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for the team not suffering even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the woodwork for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had less time to recover, Cunha levelled three minutes later when he latched onto a pass from substitute Joshua Zirkzee and guided a shot underneath rushing 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 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 sympathise with that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired against a post in the dying moments.
The draw prolongs the home side's unbeaten run to seven games, their longest such streak since 2001, and takes them eight points 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 Misfire Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood 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 options.
It's not that the missing pair are the answer to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for the equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the hostile edge was not as pronounced as in other fixtures.
The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that struck 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' 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 the club to deal with.
When they endured a poor run of form earlier in the season, many speculated about the manager's future.
In contrast, he is now overseeing significant improvement.
The task is not completed yet but step by step, Leeds are getting nearer to securing their survival.
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. The Red Devils face a Premier League trip to Burnley before also beginning their cup journey with a home tie.
