Key Moments
- Calvert-Lewin watches a first-half header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed strike in the second period.
- Cunha equalises just three minutes later.
- Leeds continue their longest top-flight undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
The Everton loanee directed a first-period attempt against the woodwork for the confident home team before Brenden Aaronson applied a cool finish with a low, 62nd-minute shot.
With the goal, 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.
Nevertheless, against a team who had less time to prepare, Cunha restored parity three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and slid a shot underneath rushing home 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 Amorim is without several key attacking players due to a combination of fitness issues and international duty.
Not that you would expect Leeds to care about that given their own lack of preparation time.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting 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 ruled out for offside much earlier in the match, also blasted against a post late on.
The point prolongs Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them a significant margin 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, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's options.
It's not that the absent players 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 campaign.
But without them, Amorim 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 Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their natural positions, alongside Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in belief 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.
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 comparatively subdued affair.
True, there were moments of expected atmosphere, but the hostile edge was not as pronounced as in other fixtures.
The home fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any length of time.
The Calvert-Lewin header that clipped the post was an rare 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 coveted win against their old foes.
Nevertheless, there is a much bigger picture for Daniel Farke and the club to deal with.
When they suffered a difficult run of form earlier in the season, many speculated about the manager's future.
Instead, he is now overseeing significant improvement.
The job is not completed yet but step by step, Leeds are getting nearer to securing 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. The Red Devils face a Premier League trip to Burnley before also beginning their cup journey with a Old Trafford tie.
