Match Summary
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed finish in the second half.
- Cunha responds only three minutes later.
- The Yorkshire side extend their longest top-flight undefeated streak since 2001.
The Red Devils' poor recent struggles continued at Leeds' fortress, but head coach Ruben Amorim had Matheus Cunha to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the post for the confident hosts before the American midfielder applied a cool finish with a low, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to recover, the forward levelled three minutes later when he ran on to a pass from substitute Joshua Zirkzee and guided a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a mix of injury and international duty.
Not that the hosts to care about that given their own tight schedule.
The Swiss attacker 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 finding it hard to make an impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The point extends the home side's unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, wasted.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's options.
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 experienced disappointing results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He evidently does not have full faith in teenager 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 recent outings, and others playing out of their natural positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in belief and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of typical fervor, but the intimidating edge was not as evident as in other encounters.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
For a short moment, 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 Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many speculated about the manager's future.
In contrast, he is now masterminding significant progress.
The task is not completed yet but gradually, the team are getting closer to achieving their top-flight status.
What Happens Next?
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their cup journey with a Old Trafford tie.
