Key Moments
- Dominic Calvert-Lewin sees a early header come back off the post.
- Brenden Aaronson puts the hosts ahead with a well-placed effort in the second period.
- Cunha equalises just three minutes afterwards.
- The Yorkshire side continue their best Premier League unbeaten run since the turn of the century.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
The Everton loanee headed a first-half effort against the post for the confident hosts before the American midfielder finished superbly with a driven, 62nd-minute effort.
With the goal, the United boss was under intense scrutiny after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had less time to recover, the forward levelled three minutes later when he ran on to a through ball from substitute the Dutchman and slid a shot 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 Amorim is without several key attacking players due to a combination of fitness issues and international duty.
Not that the hosts to care about 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 United heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the match, also blasted against a post late on.
The draw extends the home side's unbeaten run to seven games, their longest 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 chance to move into the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: Amorim's Side Struggle Again
With the AFCON reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other attackers is having on Amorim's options.
It's not that the absent players 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, the boss has few attacking options.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in confidence and assurance 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 United Breakdown: A Further Step Towards Survival
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments 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 inability 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 struggling when a defensive error opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for the manager and the club to deal with.
When they endured a poor run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now overseeing clear improvement.
The job is not done yet but step by step, Leeds are getting closer to securing their survival.
Looking Ahead
The Yorkshire club have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also entering their cup journey with a home tie.
