Key Moments
The Red Devils' poor run of form continued at Leeds' fortress, but manager Ruben Amorim had Matheus Cunha to thank for his side avoiding even more damage against their old rivals.
The Everton loanee directed a first-half effort against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had less time to recover, the forward restored parity three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and guided a shot underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without four key attacking players due to a mix of fitness issues and national team commitments.
Not that you would expect the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The draw prolongs Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the involved countries make a swift 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 experienced poor results earlier in the season.
But without them, the boss has few attacking options.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost immediately after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and conviction in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the new signing.
After memorable 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 previous fixtures.
Leeds' fans were more concerned about their side's inability to get sustained possession in dangerous areas for any length of time.
The striker's header that struck the post was an isolated 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 the opener.
For a short moment, The home delirious fans thought they were about to secure a rare win against Manchester United.
However, there is a much bigger picture for the manager and Leeds 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 clear progress.
The task is not completed yet but gradually, the team are getting closer to achieving their survival.
The Yorkshire club have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their cup journey with a Old Trafford tie.
