Key Moments
- Calvert-Lewin sees a first-half header ricochet off the post.
- Brenden Aaronson puts the home side ahead with a well-placed finish in the second half.
- Matheus Cunha responds only three minutes later.
- The Yorkshire side continue their best top-flight unbeaten run since 2001.
The Red Devils' poor recent struggles persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
The Everton loanee headed a first-period effort against the woodwork for the in-form hosts before the American midfielder 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 Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to recover, Cunha restored parity three minutes after the opener when he latched onto a pass from substitute the Dutchman and slid a finish underneath rushing home goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a mix of fitness issues and international duty.
Not that you would expect the hosts to care about that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw prolongs Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, squandered.
Man Utd Analysis: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the participating nations make a swift exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated 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 suffered disappointing results earlier in the season.
But without them, the boss has few attacking options.
He clearly does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the expensive 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 United Breakdown: A Further Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of expected atmosphere, but the hostile edge was not as pronounced as in other encounters.
The home fans were more concerned about their side's inability to get sustained possession in advanced areas for any prolonged period.
The striker's header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were struggling when a defensive error opened the door for the opener.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against Manchester United.
However, there is a wider context for Daniel Farke and the club to deal with.
When they endured a difficult run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now masterminding clear improvement.
The task is not completed yet but gradually, Leeds are getting closer to achieving their top-flight status.
What Happens Next?
