At a Glance
- Dominic Calvert-Lewin sees a early header come back off the post.
- Aaronson puts the home side ahead with a well-placed finish in the second half.
- Cunha equalises only three minutes afterwards.
- Leeds extend their best top-flight unbeaten run since 2001.
The Red Devils' disappointing run of form persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
The Everton loanee directed a first-half attempt against the woodwork for the confident home team before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
With the goal, the United boss was under intense scrutiny after his side had failed to beat struggling Wolves at home earlier in the week.
However, against opponents who had two days less to prepare, Cunha restored parity three minutes later when he latched onto a through ball from substitute Joshua Zirkzee and slid a finish underneath advancing 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 the manager is without several key attacking players due to a mix of injury and national team commitments.
Not that you would expect Leeds to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also blasted against a post late on.
The point prolongs the home side's unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other attackers is having on the team's squad.
It's not that the missing pair are the answer 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 alternatives in attack.
He evidently does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to 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: Another Step Towards Survival
After thrilling victories in their last few home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as evident as in other fixtures.
The home fans were more preoccupied about their side's inability 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 quality in a congested first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for the opener.
Ever so briefly, Leeds' ecstatic 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 endured a poor run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now masterminding clear progress.
The task is not done yet but step by step, Leeds are getting closer to achieving their survival.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also entering their FA Cup journey with a Old Trafford tie.
