At a Glance
- Dominic Calvert-Lewin watches a first-half header come back off the post.
- Aaronson puts the hosts ahead with a low strike in the second half.
- Cunha equalises just three minutes later.
- Leeds continue their longest top-flight unbeaten run since the turn of the century.
The Red Devils' poor recent struggles persisted at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-period attempt against the post for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
However, against opponents who had two days less to prepare, Cunha restored parity three minutes later when he latched onto a through ball from introduced the Dutchman and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and international duty.
Not that you would expect Leeds to sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and United 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.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired against a post in the dying moments.
The point extends 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 relegation zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's squad.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that suffered 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 seasoned Joshua Zirkzee, even though the Netherlands forward delivered the through ball for Cunha's equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
Leeds Analysis: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were instances of typical fervor, but the intimidating edge was not as evident as in other fixtures.
The home fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The striker's header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for the opener.
Ever so briefly, The home ecstatic fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's future.
In contrast, he is now masterminding clear improvement.
The task is not done yet but step by step, Leeds are getting nearer to achieving their top-flight status.
Looking Ahead
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 league trip to Burnley before also entering their cup journey with a Old Trafford tie.
