Key Moments
- Calvert-Lewin watches a first-half header come back off the post.
- Brenden Aaronson puts the home side ahead with a low strike in the second half.
- Cunha equalises only three minutes later.
- The Yorkshire side continue their longest Premier League unbeaten run since 2001.
The Red Devils' disappointing run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more disappointment against their old rivals.
The Everton loanee directed a first-period attempt against the post for the in-form hosts before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had less time to prepare, the forward levelled three minutes after the opener when he latched onto a through ball from introduced 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 the manager is without four key attacking players due to a mix of injury and national team commitments.
Not that the hosts to care about that given their own lack of preparation time.
The Swiss attacker 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 struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post in the dying moments.
The draw 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 relegation zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, wasted.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on the team's squad.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, Amorim has limited attacking options.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and assurance 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: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of typical atmosphere, but the hostile edge was not as evident as in other encounters.
The home fans were more preoccupied about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The striker's header that struck 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 Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for Daniel Farke 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 task is not completed yet but gradually, the team are getting closer to securing their survival.
What Happens Next?
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 Premier League trip to Burnley before also beginning their cup journey with a Old Trafford tie.
