Match Summary
- Calvert-Lewin sees a early header come back off the upright.
- Brenden Aaronson fires the hosts ahead with a well-placed finish in the second period.
- Cunha levels only three minutes later.
- Leeds extend their longest Premier League undefeated streak since 2001.
Manchester United's disappointing run of form continued at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-period attempt against the post for the confident hosts before the American midfielder applied a cool finish with a low, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had failed to beat struggling Wolves at home 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 through ball from introduced Joshua Zirkzee and guided a shot underneath advancing Leeds 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 mix of fitness issues and national team commitments.
Not that you would expect the hosts 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 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 close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The point extends Leeds' unbeaten run to seven games, their best 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 opportunity to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: Amorim'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 pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team's options.
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 suffered poor results earlier in the season.
But without them, the boss has limited alternatives in attack.
He clearly does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the through ball for Cunha's equaliser almost instantly after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in five games, 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 confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds Analysis: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of expected fervor, but the intimidating edge was not as evident as in other fixtures.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's future.
In contrast, he is now overseeing significant improvement.
The task is not completed yet but gradually, the team are getting closer to achieving their top-flight status.
What Happens Next?
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also entering their cup journey with a home tie.
