Key Moments
- Calvert-Lewin watches a first-half header ricochet off the post.
- Aaronson puts the home side ahead with a well-placed effort in the second half.
- Cunha equalises only three minutes later.
- Leeds extend their best top-flight undefeated streak since the turn of the century.
The Red Devils' poor run of form persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
The Everton loanee directed a first-half effort against the post for the confident hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had less time to prepare, the forward levelled three minutes after the opener when he ran on to a through ball from substitute Joshua Zirkzee and guided a finish underneath rushing home 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 Amorim is without four key attacking players due to a combination of injury and national team commitments.
Not that you would expect Leeds to care about that given their own lack of preparation time.
Noah Okafor forced a diving 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 impact, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw extends the home side's unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a short time, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's squad.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in confidence 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: Another Step Towards Safety
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 typical 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 worthwhile possession in advanced areas for any length of time.
The striker's header that struck the post was an rare moment of quality in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a poor 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 gradually, the team are getting closer to achieving their survival.
Looking Ahead
Leeds have a top-flight trip to St James' Park 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 entering their cup journey with a home tie.
