At a Glance
- Calvert-Lewin watches a early header come back off the post.
- Aaronson puts the home side ahead with a low effort in the second half.
- Matheus Cunha levels just three minutes afterwards.
- The Yorkshire side extend their best top-flight undefeated streak since the turn of the century.
The Red Devils' disappointing run of form persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for the team not suffering even more damage against Leeds.
The Everton loanee directed a first-half effort against the woodwork for the confident hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had two days less to recover, Cunha restored parity three minutes later when he ran on to a through ball from introduced Joshua Zirkzee and guided a finish underneath rushing Leeds 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 mix of injury and national team commitments.
Not that you would expect the hosts to care about that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned Zirkzee'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 draw prolongs the home side's 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 the Champions League places, albeit only for a matter of hours, squandered.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the involved countries make a swift exit.
Existing 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 options.
It's not that the missing pair 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, Amorim has few alternatives in attack.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous struggling 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.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their last few home games, the arrival of their fiercest 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 fixtures.
Leeds' fans were more concerned about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were struggling when a defensive error opened the door for the opener.
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 the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's future.
In contrast, he is now overseeing clear progress.
The task is not done yet but step by step, Leeds are getting nearer to securing their survival.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
