At a Glance
- Calvert-Lewin sees a early header come back off the upright.
- Aaronson fires the home side ahead with a well-placed finish in the second period.
- Cunha responds only three minutes later.
- The Yorkshire side extend their longest Premier League undefeated streak since 2001.
The Red Devils' disappointing run of form 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 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 effort.
With the goal, the United boss was under intense scrutiny after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against opponents who had two days less to recover, Cunha restored parity three minutes after the opener when he ran on to a pass from substitute Joshua Zirkzee and guided 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 mix of injury and national team commitments.
Not that the hosts 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 Benjamin Sesko, who is finding it hard to make an impact, 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 in the dying moments.
The point extends Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its knockout phase, the United coach could be understood for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other forwards is having on the team's squad.
It's not that the absent players are the answer to all of United's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, Amorim has limited attacking options.
He evidently does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Safety
After memorable victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as evident as in other encounters.
Leeds' fans were more preoccupied about their side's struggle 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 Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for the manager and the club to deal with.
When they endured a poor run of form earlier in the season, many speculated about the manager's position.
In contrast, he is now masterminding significant progress.
The task is not done yet but gradually, the team are getting closer to securing their top-flight status.
Looking Ahead
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
