Match Summary
- Calvert-Lewin watches a first-half header ricochet off the upright.
- Aaronson puts the home side ahead with a low strike in the second period.
- Cunha equalises only three minutes later.
- Leeds continue their best Premier League undefeated streak since 2001.
The Red Devils' disappointing run of form persisted at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period effort against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against opponents who had two days less to recover, Cunha restored parity three minutes after the opener when he latched onto a through ball from substitute the Dutchman and slid a finish underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a mix of injury and national team commitments.
Not that Leeds to sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, 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 prolongs 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 visitors though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team's squad.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that experienced poor results earlier in the season.
But without them, the boss has few attacking options.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost immediately after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of expected fervor, but the hostile edge was not as pronounced as in other fixtures.
The home fans were more concerned about their side's inability to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an isolated moment of quality 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 ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's position.
Instead, he is now overseeing clear progress.
The job is not completed yet but gradually, the team are getting closer to achieving their top-flight status.
Looking Ahead
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their cup journey with a Old Trafford tie.
