Match Summary
- Calvert-Lewin sees a first-half header ricochet off the post.
- Brenden Aaronson fires the home side ahead with a low finish in the second half.
- Cunha equalises just three minutes later.
- The Yorkshire side continue their longest top-flight unbeaten run since the turn of the century.
The Red Devils' disappointing run of form continued at Elland Road, but manager Ruben Amorim had Matheus Cunha to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-half effort against the post for the confident hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
At that stage, the United boss was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
However, against a team who had less time to prepare, the forward restored parity three minutes later when he latched onto a pass from substitute Joshua Zirkzee and guided a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without several key attacking players due to a mix of fitness issues and national team commitments.
Not that you would expect Leeds to care about that given their own tight schedule.
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 six yards out.
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 matches, their best such streak since 2001, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a short time, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers is having on the team's squad.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in confidence 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.
Leeds United Breakdown: Another Step Towards Safety
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of typical fervor, but the intimidating edge was not as pronounced as in other fixtures.
The home fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any length of time.
The striker's header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' 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 season, many thought about the manager's position.
Instead, he is now overseeing clear progress.
The job is not done yet but step by step, the team are getting nearer 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 FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their FA Cup journey with a home tie.
