Key Moments
- Dominic Calvert-Lewin sees a first-half header come back off the upright.
- Brenden Aaronson fires the home side ahead with a low effort in the second half.
- Cunha levels just three minutes afterwards.
- Leeds extend their longest top-flight unbeaten run since 2001.
The Red Devils' poor recent struggles persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for the team avoiding even more damage against their old rivals.
The Everton loanee headed a first-period attempt against the woodwork for the confident hosts before the American midfielder applied a cool finish with a low, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to prepare, the forward levelled three minutes later when he ran on to a through ball from substitute the Dutchman and guided a shot 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 Amorim is without four key attacking players due to a mix of fitness issues and international duty.
Not that the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw prolongs the home side's 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 the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Existing 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 answer to all of United's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, Amorim has few attacking options.
He clearly does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the expensive frontman looks no better than previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of typical fervor, but the hostile edge was not as pronounced as in previous fixtures.
The home fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The Calvert-Lewin header that struck the post was an rare moment of quality in a tight first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a coveted win against their old foes.
However, there is a much bigger picture for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's future.
Instead, he is now overseeing significant progress.
The task is not done yet but step by step, the team are getting closer to securing their survival.
What Happens Next?
