At a Glance
- Dominic Calvert-Lewin watches a early header come back off the post.
- Aaronson puts the home side ahead with a well-placed finish in the second period.
- Matheus Cunha responds only three minutes later.
- The Yorkshire side continue their longest Premier League undefeated streak since the turn of the century.
The Red Devils' poor recent struggles persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period effort against the post for the in-form home team before the American midfielder finished superbly with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
However, against a team who had less time to recover, the forward levelled three minutes after the opener when he latched onto a pass from introduced Joshua Zirkzee and slid a shot underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a combination of injury and international duty.
Not that Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The point prolongs the home side's unbeaten run to seven matches, their best 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 fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team'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 experienced disappointing results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home the 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 comparatively subdued affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more preoccupied about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were struggling when a defensive error opened the door for Aaronson.
For a short moment, The home ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for the manager and the club to deal with.
When they suffered a poor run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now masterminding clear improvement.
The task is not completed yet but gradually, the team are getting nearer to achieving their top-flight status.
What Happens Next?
