Key Moments
The Red Devils' poor recent struggles continued at Elland Road, but manager Ruben Amorim had Matheus Cunha to thank for the team not suffering even more disappointment against Leeds.
The Everton loanee directed a first-half effort against the woodwork for the in-form home team before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to recover, Cunha levelled three minutes after the opener when he ran on to a pass from substitute Joshua Zirkzee and slid a finish underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a combination of injury and national team commitments.
Not that the hosts to sympathise with that given their own lack of preparation time.
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 struggling to make an impression, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired against a post in the dying moments.
The draw extends the home side's unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, wasted.
With the AFCON reaching its latter stages, the United coach 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 exacerbated the impact the absence of other forwards is having on Amorim's squad.
It's not that the absent players are the answer to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, the boss has few alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in recent outings, and others playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous underwhelming signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
After memorable victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were instances of expected atmosphere, but the hostile edge was not as pronounced as in previous encounters.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that struck the post was an rare moment of threat in a congested 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 suffered a poor run of form earlier in the season, many speculated about the manager's position.
In contrast, he is now masterminding significant progress.
The job is not done yet but step by step, Leeds are getting nearer to securing their survival.
