Key Moments
- Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson puts the hosts ahead with a low finish in the second half.
- Cunha responds just three minutes later.
- The Yorkshire side continue their best Premier League undefeated streak since 2001.
The Red Devils' disappointing recent struggles continued at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for his side not suffering even more disappointment against their old rivals.
The Everton loanee directed a first-period effort against the post for the confident home team before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, the United boss was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward restored parity three minutes after the opener when he ran on to a pass from substitute Joshua Zirkzee and slid a shot underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian'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 combination of injury and international duty.
Not that you would expect the hosts to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a diving 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 six yards out.
Cunha, who had a goal disallowed for offside much earlier in the match, also blasted against a post late on.
The draw prolongs the home side's unbeaten run to seven games, their best such streak since over two decades ago, and takes them a significant margin 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.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a swift exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team'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 experienced disappointing results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
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 instantly after his arrival as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds Analysis: Another Step Towards Safety
After thrilling 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 atmosphere, but the intimidating edge was not as evident as in previous encounters.
The home fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any length of time.
The striker's header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for the opener.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the season, many speculated about the manager's future.
Instead, he is now masterminding significant progress.
The task is not completed yet but step by step, Leeds are getting closer to achieving their survival.
Looking Ahead
The Yorkshire club have a top-flight trip to St James' Park 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 FA Cup journey with a Old Trafford tie.
