Key Moments
Manchester United's poor recent struggles continued at Elland Road, but head coach Ruben Amorim had Matheus Cunha to thank for his side not suffering even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the post for the confident home team before the American midfielder finished superbly with a driven, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had two days less to recover, Cunha restored parity three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and guided a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without several key attacking players due to a mix of injury and national team commitments.
Not that the hosts to sympathise with 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 finding it hard 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 contest, also blasted 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 relegation zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a short time, wasted.
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's options.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that suffered poor results earlier in the season.
But without them, Amorim has limited alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous underwhelming signings, lacking in confidence and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of expected fervor, but the hostile edge was not as evident as in previous fixtures.
The home fans were more concerned about their side's inability to get worthwhile possession in advanced 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 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.
Nevertheless, there is a much bigger picture for the manager and the club to deal with.
When they endured a difficult run of form earlier in the season, many speculated about the manager's future.
In contrast, he is now masterminding significant progress.
The task is not done yet but gradually, the team are getting nearer to securing their top-flight status.
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also beginning their cup journey with a home tie.
