Key Moments
- Calvert-Lewin watches a first-half header ricochet off the post.
- Aaronson fires the hosts ahead with a well-placed effort in the second half.
- Cunha equalises just three minutes later.
- The Yorkshire side extend their longest Premier League undefeated streak since the turn of the century.
The Red Devils' poor run of form continued at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
Nevertheless, against a team who had less time to prepare, Cunha levelled three minutes later when he latched onto a pass from introduced the Dutchman and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a mix of fitness issues and international duty.
Not that Leeds to sympathise with that given their own tight schedule.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, 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 in the dying moments.
The point prolongs the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them eight points 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.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on the team's options.
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, Amorim has limited attacking options.
He evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in belief and conviction 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 Analysis: A Further Step Towards Survival
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of expected atmosphere, but the intimidating edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's struggle to get sustained possession in dangerous areas for any length of time.
The striker's header that struck the post was an isolated moment of threat in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for Daniel Farke and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now masterminding clear improvement.
The task is not completed yet but gradually, Leeds are getting closer to achieving their top-flight status.
Looking Ahead
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their cup journey with a Old Trafford tie.
