Key Moments
- Calvert-Lewin sees a first-half header come back off the upright.
- Brenden Aaronson fires the home side ahead with a low finish in the second half.
- Cunha levels only three minutes later.
- The Yorkshire side continue their best top-flight undefeated streak since the turn of the century.
The Red Devils' disappointing run of form continued at Elland Road, but head coach Ruben Amorim had Matheus Cunha to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the post for the in-form hosts before the American midfielder finished superbly with a driven, 62nd-minute effort.
At that stage, the United boss was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against opponents who had less time to recover, the forward restored parity three minutes later when he latched onto a pass from introduced the Dutchman and guided a finish underneath advancing 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 Amorim is without several key attacking players due to a combination of fitness issues and national team commitments.
Not that you would expect Leeds to sympathise with 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 Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the match, also blasted against a post late on.
The point prolongs the home side's unbeaten run to seven games, their longest such streak since 2001, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a short time, wasted.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on Amorim's options.
It's not that the missing pair are the answer 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 few attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost immediately after his arrival as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in belief 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.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin 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 Daniel Farke and the club to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's position.
In contrast, he is now overseeing clear progress.
The job is not done yet but step by step, Leeds are getting closer to achieving their top-flight status.
What Happens Next?
The Yorkshire club 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 league trip to Turf Moor before also beginning their cup journey with a home tie.
