At a Glance
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Brenden Aaronson fires the home side ahead with a well-placed strike in the second half.
- Cunha levels just three minutes afterwards.
- The Yorkshire side extend their longest Premier League unbeaten run since the turn of the century.
Manchester United's poor run of form continued at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-period effort against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
With the goal, the United boss was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had less time to prepare, Cunha levelled three minutes after the opener when he latched onto a pass from substitute the Dutchman and guided a finish underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League 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 care about that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting 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.
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 Leeds' 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 Manchester United though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a swift exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other attackers is having on the team'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 few attacking options.
He evidently does not have full faith in youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost immediately after his arrival as a replacement.
That leaves Cunha, 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 no better than previous struggling 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 young striker.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the hostile edge was not as pronounced as in other encounters.
The home fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
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' delirious fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's future.
In contrast, he is now overseeing clear improvement.
The task is not completed yet but step by step, Leeds are getting closer to securing their survival.
Looking Ahead
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 Burnley before also beginning their FA Cup journey with a home tie.
