Key Moments
- Dominic Calvert-Lewin sees a early header come back off the post.
- Brenden Aaronson fires the home side ahead with a well-placed strike in the second period.
- Cunha levels just three minutes afterwards.
- Leeds extend their longest top-flight unbeaten run since 2001.
The Red Devils' poor recent struggles continued at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-period attempt against the woodwork for the in-form home team before the American midfielder applied a cool finish with a low, 62nd-minute shot.
At that stage, the United boss 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.
However, against a team who had less time to recover, Cunha levelled three minutes later when he latched onto a through ball from substitute Joshua Zirkzee and guided a finish underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian'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 injury and national team commitments.
Not that 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 audacious 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 six yards out.
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 matches, their best such streak since 2001, and takes them eight points 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 matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood 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 forwards is having on the team's squad.
It's not that the absent players are the answer to all of United's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost immediately after his introduction 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 Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of expected atmosphere, but the hostile edge was not as pronounced as in previous fixtures.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of threat in a tight first half.
It still felt as though the hosts were struggling when a mistake opened the door for the opener.
Ever so briefly, The home delirious fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for Daniel Farke 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 masterminding significant improvement.
The task is not completed yet but gradually, the team are getting closer to securing their top-flight status.
