Key Moments
- Calvert-Lewin watches a first-half header come back off the upright.
- Brenden Aaronson puts the hosts ahead with a low strike in the second half.
- Cunha levels only three minutes afterwards.
- The Yorkshire side continue their longest top-flight unbeaten run since the turn of the century.
The Red Devils' disappointing run of form continued at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for the team not suffering even more disappointment against Leeds.
Dominic Calvert-Lewin headed a first-half effort against the woodwork for the confident hosts 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 been held by struggling Wolves at home earlier in the week.
Nevertheless, against a team who had two days less to prepare, Cunha levelled three minutes after the opener when he ran on to a pass from substitute the Dutchman and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a combination of injury and international duty.
Not that Leeds to care about that given their own lack of preparation time.
The Swiss attacker 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 struggling 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 match, also fired against a post in the dying moments.
The draw extends Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them eight points clear of the drop 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 Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated 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 United's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others playing out of their natural positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in belief and conviction 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 Analysis: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of expected fervor, but the hostile edge was not as pronounced as in other encounters.
The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated 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' ecstatic fans thought they were about to secure a rare win against Manchester United.
However, there is a much bigger picture for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now masterminding significant improvement.
The task is not done yet but step by step, Leeds are getting closer to securing their top-flight status.
What Happens Next?
The Yorkshire club 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 league trip to Burnley before also entering their cup journey with a Old Trafford tie.
