Key Moments
- Calvert-Lewin watches 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 responds only three minutes afterwards.
- The Yorkshire side continue their longest Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing run of form continued at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period effort against the post for the confident hosts before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
However, against a team who had less time to prepare, Cunha levelled three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth 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 fitness issues and international duty.
Not that you would expect Leeds to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a diving 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 impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also fired against a post late on.
The point extends the home side's unbeaten run to seven games, their best such streak since over two decades ago, 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, squandered.
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 participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's options.
It's not that the absent players are the answer to all of United's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, the boss has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored three goals 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 belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were instances of typical atmosphere, but the hostile edge was not as evident as in previous fixtures.
Leeds' fans were more concerned 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 tight first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for the opener.
For a short moment, The home delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, 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 masterminding clear progress.
The task is not completed yet but gradually, the team are getting closer to achieving their top-flight status.
What Happens Next?
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their cup journey with a home tie.
