Match Summary
The Red Devils' disappointing run of form continued at Elland Road, but manager Ruben Amorim had Matheus Cunha to thank for the team avoiding even more disappointment against their old rivals.
The Everton loanee directed a first-half effort against the post for the confident home team before Brenden Aaronson applied a cool finish with a driven, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
However, against a team who had less time to recover, the forward levelled three minutes later when he ran on to a through ball from introduced Joshua Zirkzee and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without several key attacking players due to a mix of injury and national team commitments.
Not that the hosts to care about that given their own tight schedule.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the match, 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 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, squandered.
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a pretty quick 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 options.
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 experienced poor results earlier in the campaign.
But without them, Amorim has limited attacking options.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous struggling signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
After memorable victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of typical fervor, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The striker's header that clipped 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 Aaronson.
For a short moment, The home ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for the manager and the club to deal with.
When they endured a difficult run of form earlier in the season, many speculated about the manager's position.
Instead, he is now masterminding significant improvement.
The task is not done yet but gradually, the team are getting nearer to achieving their survival.
