Match Summary
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Brenden Aaronson fires the home side ahead with a low effort in the second period.
- Cunha equalises just three minutes later.
- The Yorkshire side continue their best Premier League unbeaten run since the turn of the century.
Manchester United's disappointing run of form persisted at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-half effort against the woodwork for the confident home team before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had two days less to prepare, Cunha restored parity three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when the manager is without four 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 diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The point extends the home side's unbeaten run to seven matches, their best such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other attackers is having on the team's options.
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 campaign.
But without them, Amorim has limited alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost immediately 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 natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in belief and conviction 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: Another Step Towards Safety
After memorable victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of typical fervor, but the intimidating edge was not as pronounced as in previous encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in advanced areas for any length of time.
The striker's header that struck the post was an rare moment of threat in a tight first half.
It still felt as though Leeds were struggling when a defensive error opened the door for the opener.
Ever so briefly, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
However, there is a wider context for Daniel Farke and the club to deal with.
When they endured a difficult run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now masterminding clear improvement.
The job is not done yet but step by step, Leeds are getting nearer to securing their top-flight status.
What Happens Next?
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their FA Cup journey with a home tie.
