Key Moments
- Dominic Calvert-Lewin watches a first-half header ricochet off the upright.
- Brenden Aaronson puts the hosts ahead with a well-placed finish in the second period.
- Cunha levels just three minutes afterwards.
- The Yorkshire side extend their longest Premier League undefeated streak since 2001.
The Red Devils' disappointing recent struggles persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side not suffering even more disappointment against Leeds.
The Everton loanee directed a first-period attempt against the woodwork for the in-form home team before the American midfielder 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 Old Trafford earlier in the week.
Nevertheless, against a team who had less time to recover, Cunha levelled three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and guided a finish underneath advancing Leeds 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 the manager is without four key attacking players due to a mix of injury and national team commitments.
Not that you would expect Leeds to sympathise with that given their own lack of preparation time.
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 struggling to make an impression, 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 point extends Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them eight points 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 matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other attackers is having on Amorim's options.
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 season.
But without them, Amorim has few alternatives in attack.
He evidently does not have full faith in youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the through ball for the equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run 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 fiercest rivals to home was a bit drab affair.
True, there were instances of typical atmosphere, but the hostile edge was not as pronounced as in other encounters.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The striker's header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were struggling when a defensive error 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.
Nevertheless, there is a much bigger picture for the manager and the club to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's future.
In contrast, he is now masterminding significant progress.
The task is not completed yet but step by step, the team are getting closer to achieving their survival.
Looking Ahead
Leeds have a Premier League 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 FA Cup journey with a Old Trafford tie.
