At a Glance
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Brenden Aaronson puts the hosts ahead with a well-placed effort in the second half.
- Matheus Cunha equalises just three minutes later.
- Leeds continue their best Premier League unbeaten run since the turn of the century.
The Red Devils' poor recent struggles continued at Elland Road, 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 headed a first-half effort against the post for the confident hosts before the American midfielder applied a cool finish with a low, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had less time to recover, Cunha restored parity three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and slid a finish underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth 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 fitness issues and national team commitments.
Not that Leeds to care about that given their own lack of preparation time.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the match, also blasted against a post late on.
The point prolongs Leeds' 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 visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on the team's squad.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as evident as in other encounters.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
For a short moment, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now masterminding significant progress.
The job is not done yet but gradually, Leeds are getting closer to achieving 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 domestic cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
