Match Summary
- Calvert-Lewin watches a early header come back off the upright.
- Brenden Aaronson fires the hosts ahead with a well-placed strike in the second period.
- Cunha responds just three minutes later.
- Leeds continue their best Premier League undefeated streak since 2001.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post 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 in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to prepare, Cunha restored parity three minutes later when he latched onto a pass from introduced Joshua Zirkzee and slid a shot underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a combination of injury and national team commitments.
Not that Leeds to care about that given their own tight schedule.
The Swiss attacker forced a full length save out of visiting 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.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The point prolongs the home side's unbeaten run to seven games, their longest 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: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim 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 absence of other attackers is having on Amorim's squad.
It's not that the missing pair are the solution to all of the club's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, the boss has few attacking options.
He evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their natural positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
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 instances of typical atmosphere, but the intimidating edge was not as pronounced as in other fixtures.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
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 the manager and the club to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's position.
Instead, he is now overseeing significant progress.
The task is not completed yet but step by step, Leeds are getting closer to achieving their top-flight status.
Looking Ahead
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
