At a Glance
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Aaronson puts the hosts ahead with a well-placed finish in the second period.
- Cunha responds just three minutes later.
- Leeds continue their longest top-flight unbeaten run since the turn of the century.
The Red Devils' disappointing run of form continued at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-half attempt against the post for the in-form hosts 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 bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had two days less to prepare, Cunha levelled three minutes later when he ran on to a pass from introduced Joshua Zirkzee and slid a finish 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 four key attacking players due to a combination of injury and international duty.
Not that you would expect the hosts to care about that given their own tight schedule.
Noah Okafor 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 struggling to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The point extends Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, 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 matter of hours, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on the team's options.
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, the boss has few alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming 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 new signing.
Leeds Analysis: Another Step Towards Safety
After memorable victories in their last few home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as evident as in other fixtures.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an rare moment of threat in a tight 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 delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager and the club to deal with.
When they endured a poor run of form earlier in the season, many speculated about the manager's position.
Instead, he is now overseeing significant progress.
The task is not done yet but gradually, the team are getting closer to securing their top-flight status.
Looking Ahead
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their FA 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.
