Match Summary
- Dominic Calvert-Lewin watches a first-half header ricochet off the upright.
- Aaronson fires the hosts ahead with a low strike in the second half.
- Cunha equalises just three minutes later.
- The Yorkshire side continue their longest 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 disappointment against their old rivals.
The Everton loanee directed a first-half effort against the post for the confident home team before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward restored parity three minutes later when he latched onto a through ball from substitute Joshua Zirkzee and slid a finish underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his big-money summer move and came at a time when Amorim is without four key attacking players due to a combination of injury and international duty.
Not that Leeds to care about 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 United heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned his teammate's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired 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 drop zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: Amorim'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 pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim'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 disappointing results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Survival
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 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 dangerous areas for any prolonged period.
The striker's header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were finding it tough 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.
However, there is a much bigger picture for Daniel Farke and the club to deal with.
