Key Moments
- Calvert-Lewin watches a first-half header ricochet off the upright.
- Aaronson puts the hosts ahead with a well-placed strike in the second period.
- Matheus Cunha responds only three minutes later.
- Leeds extend their best Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against Leeds.
The Everton loanee directed a first-half attempt against the post for the in-form hosts before the American midfielder finished superbly with a driven, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had been held by bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against a team who had two days less to recover, Cunha levelled three minutes after the opener when he ran on to a through ball from introduced the Dutchman and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a combination of fitness issues and national team commitments.
Not that you would expect the hosts to care about that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the match, also blasted against a post late on.
The point prolongs Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them a significant margin clear of the drop 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 AFCON reaching its knockout phase, the United coach 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 squad.
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 few alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for the equaliser almost instantly after his arrival as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in belief 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 young striker.
Leeds Analysis: Another Step Towards Survival
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 expected fervor, but the hostile edge was not as pronounced as in other fixtures.
Leeds' fans were more concerned about their side's inability to get worthwhile possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were struggling when a defensive error 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 Daniel Farke and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now masterminding clear improvement.
The job is not completed yet but gradually, the team are getting nearer to achieving their top-flight status.
Looking Ahead
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Turf Moor before also entering their FA Cup journey with a Old Trafford tie.
