Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the post.
- Brenden Aaronson fires the home side ahead with a low strike in the second period.
- Cunha equalises just three minutes afterwards.
- The Yorkshire side continue their best Premier League undefeated streak since 2001.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for his side not suffering even more disappointment against their old rivals.
The Everton loanee directed a first-period attempt against the woodwork for the confident home team before the American midfielder finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to recover, the forward restored parity three minutes after the opener when he ran on to a through ball from introduced Joshua Zirkzee and slid a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his big-money 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 the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United 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 his teammate'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 prolongs Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a swift exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other attackers is having on the team's options.
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 experienced disappointing results earlier in the campaign.
But without them, the boss has limited attacking options.
He clearly does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous struggling signings, lacking in belief and conviction in front of goal.
His 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 Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of typical fervor, but the hostile edge was not as pronounced as in previous fixtures.
The home fans were more preoccupied about their side's inability to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that clipped the post was an rare moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
For a short moment, The home ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for the manager and the club to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's position.
Instead, he is now overseeing clear improvement.
The task is not completed yet but gradually, the team are getting closer to securing their survival.
Looking Ahead
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also entering their cup journey with a home tie.
