Key Moments
- Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson fires the home side ahead with a low strike in the second period.
- Matheus Cunha levels only three minutes afterwards.
- The Yorkshire side continue their best Premier League unbeaten run since 2001.
The Red Devils' disappointing run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more damage against Leeds.
The Everton loanee directed a first-period effort against the woodwork for the confident home team before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
Nevertheless, against opponents who had two days less to recover, the forward levelled three minutes after the opener when he ran on to a through ball from substitute the Dutchman and guided a shot underneath advancing home 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 Amorim is without several key attacking players due to a combination of injury and national team commitments.
Not that 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 spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The point extends the home side's unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them a significant margin 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.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence 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 few attacking options.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost instantly after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in recent outings, and others playing out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous struggling 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 Analysis: A Further Step Towards Safety
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of expected fervor, but the intimidating edge was not as pronounced as in previous encounters.
The home fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an rare moment of threat in a tight 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' delirious fans thought they were about to secure a coveted win against their old foes.
Nevertheless, 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 season, many speculated about the manager's position.
In contrast, he is now masterminding significant improvement.
The task is not done yet but step by step, Leeds are getting closer to securing their survival.
Looking Ahead
The Yorkshire club 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 league trip to Turf Moor before also entering their cup journey with a Old Trafford tie.
