Key Moments
- Calvert-Lewin sees a early header come back off the upright.
- Brenden 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 unbeaten run since 2001.
The Red Devils' poor run of form continued at Leeds' fortress, but head coach Ruben Amorim had Matheus Cunha to thank for the team not suffering even more damage against their old rivals.
The Everton loanee headed a first-half attempt against the woodwork for the in-form home team before the American midfielder finished superbly with a low, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny 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 less time to recover, Cunha levelled three minutes after the opener when he latched onto a pass from substitute Joshua Zirkzee and guided a shot underneath rushing home goalkeeper Lucas Perri.
It was only the South American'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 combination of injury and national team commitments.
Not that you would expect 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 impact, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven games, 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, squandered.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Existing 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 missing pair are the answer to all of the club's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He evidently does not trust youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Sesko.
On this showing, the expensive frontman looks similar to previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected fervor, but the intimidating edge was not as pronounced as in other fixtures.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The striker's header that clipped the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were struggling when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a rare win against their old foes.
However, 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 thought about the manager's future.
Instead, he is now overseeing significant improvement.
The task is not completed yet but step by step, the team are getting closer to achieving their top-flight status.
What Happens Next?
The Yorkshire club 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 Premier League trip to Burnley before also beginning their cup journey with a Old Trafford tie.
