Match Summary
- Dominic Calvert-Lewin watches a first-half header come back off the upright.
- Aaronson puts the hosts ahead with a low strike in the second half.
- Cunha equalises just three minutes afterwards.
- The Yorkshire side extend their longest top-flight 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 his side not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-half effort against the woodwork for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
However, against a team who had two days less to prepare, the forward levelled three minutes later when he latched onto a through ball from introduced the Dutchman and guided a shot underneath rushing home goalkeeper Lucas Perri.
It was only the South American's fourth 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 fitness issues and international duty.
Not that you would expect the hosts to sympathise with 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 Benjamin Sesko, who is finding it hard to make an impression, turned his teammate's cut-back wide from close range.
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 games, their longest such streak since 2001, 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 matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's options.
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 suffered disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in recent outings, and others playing out of their natural positions, alongside Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their last few home games, the arrival of their fiercest 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 previous fixtures.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for the opener.
For a short moment, The home ecstatic fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a much bigger picture for Daniel Farke and the club to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's position.
Instead, he is now masterminding clear progress.
The task is not completed yet but step by step, Leeds are getting nearer to achieving their top-flight status.
