Key Moments
- Calvert-Lewin watches a first-half header come back off the post.
- Brenden Aaronson fires the home side ahead with a low finish in the second period.
- Cunha responds only three minutes afterwards.
- Leeds extend their longest top-flight undefeated streak since the turn of the century.
The Red Devils' poor run of form continued at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more disappointment against Leeds.
The Everton loanee directed a first-half effort against the woodwork for the confident hosts before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had less time to recover, Cunha restored parity three minutes after the opener when he latched onto a pass from introduced the Dutchman and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a combination of injury and national team commitments.
Not that you would expect Leeds to sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United 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.
Cunha, who had a goal ruled out for offside much earlier in the match, also blasted against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to skipper 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 missing pair are the solution to all of the club's problems. After all, they were part of the side that experienced poor results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and assurance 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 young striker.
Leeds Analysis: Another Step Towards Survival
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as pronounced as in other encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in advanced areas for any prolonged period.
The striker's header that clipped the post was an rare moment of quality in a tight first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for the opener.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
However, there is a wider context for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's position.
Instead, he is now overseeing clear improvement.
The job is not completed yet but step by step, the team are getting closer to achieving their survival.
Looking Ahead
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a Premier League trip to Turf Moor before also beginning their cup journey with a Old Trafford tie.
