Key Moments
- Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson fires the home side ahead with a well-placed strike in the second period.
- Matheus Cunha levels just three minutes afterwards.
- The Yorkshire side extend their best top-flight unbeaten run since the turn of the century.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for the team avoiding even more damage against their old rivals.
The Everton loanee headed a first-period effort against the woodwork for the confident home team 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 failed to beat bottom-of-the-table Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha restored parity three minutes later when he latched onto a pass from introduced Joshua Zirkzee and guided a shot underneath advancing 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 injury and international duty.
Not that you would expect the hosts to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impression, turned his teammate's cut-back wide from close range.
Cunha, 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 matches, their best such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on the team's squad.
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 disappointing results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming 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 thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as evident as in previous encounters.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any length of time.
The striker's header that clipped the post was an rare moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context 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 position.
In contrast, he is now masterminding clear improvement.
The task is not done yet but gradually, Leeds are getting closer to achieving their survival.
Looking Ahead
The Yorkshire club have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also entering their cup journey with a Old Trafford tie.
