Key Moments
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson fires the home side ahead with a low finish in the second period.
- Matheus Cunha levels just three minutes later.
- The Yorkshire side extend their best top-flight undefeated streak since the turn of the century.
Manchester United's poor run of form continued at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for the team not suffering even more damage against Leeds.
Dominic Calvert-Lewin directed a first-period attempt against the woodwork for the confident home team before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had less time 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 the manager 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 lack of preparation time.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven games, their best such streak since over two decades ago, and takes them eight points 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, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the participating nations 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 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 poor results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost instantly 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 expensive frontman looks no better than previous struggling signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds Analysis: Another Step Towards Survival
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of typical fervor, but the hostile edge was not as pronounced as in other fixtures.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The striker's header that struck the post was an rare moment of threat in a tight first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager and the club to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's future.
Instead, he is now masterminding clear progress.
The job is not done yet but step by step, Leeds are getting nearer to securing their survival.
Looking Ahead
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Turf Moor before also beginning their FA Cup journey with a home tie.
