Match Summary
- Dominic Calvert-Lewin watches a early header come back off the upright.
- Brenden Aaronson puts the home side ahead with a low strike in the second period.
- Cunha levels only three minutes later.
- The Yorkshire side extend their longest Premier League undefeated streak since 2001.
The Red Devils' poor recent struggles continued at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-half effort against the woodwork for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
With the goal, the United boss was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had less time to prepare, Cunha levelled three minutes later when he latched onto a through ball from introduced the Dutchman and guided a finish underneath rushing home 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 national team commitments.
Not that you would expect the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling 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 match, also blasted against a post late on.
The draw prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other attackers is having on Amorim's squad.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, the boss has limited alternatives in attack.
He evidently does not trust youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home the 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 home was a comparatively subdued affair.
True, there were instances of typical atmosphere, but the hostile edge was not as evident as in previous encounters.
The home 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 clipped the post was an isolated moment of threat in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's position.
Instead, he is now overseeing significant progress.
The task is not done yet but gradually, the team are getting nearer to achieving their top-flight status.
What Happens Next?
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their cup journey with a Old Trafford tie.
