Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed strike in the second half.
- Matheus Cunha levels just three minutes later.
- Leeds extend their longest Premier League unbeaten run since the turn of the century.
The Red Devils' disappointing run of form continued at Elland Road, but head coach the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more disappointment against Leeds.
The Everton loanee headed a first-period attempt against the woodwork for the confident home team before the American midfielder finished superbly with a low, 62nd-minute effort.
With the goal, the United boss was under intense scrutiny after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had less time to recover, Cunha restored parity three minutes later when he latched onto a through ball from substitute Joshua Zirkzee and guided a shot underneath advancing 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 several key attacking players due to a mix of injury and international duty.
Not that the hosts to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned his teammate'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 point prolongs the home side's unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's options.
It's not that the missing pair are the solution to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, Amorim has few attacking options.
He clearly does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home the 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 last few home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the hostile edge was not as pronounced as in other fixtures.
Leeds' fans were more concerned about their side's inability to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a coveted win against their old foes.
However, there is a much bigger picture for Daniel Farke and the club to deal with.
When they endured a difficult run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now overseeing clear improvement.
The task is not done yet but gradually, Leeds are getting closer to achieving their top-flight status.
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 Turf Moor before also beginning their FA Cup journey with a home tie.
