Key Moments
- Dominic Calvert-Lewin watches a early header ricochet off the post.
- Aaronson fires the home side ahead with a low finish in the second half.
- Cunha equalises only three minutes later.
- Leeds continue their best Premier League undefeated streak since the turn of the century.
The Red Devils' poor run of form continued at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
Dominic Calvert-Lewin directed a first-half effort against the woodwork for the in-form home team before Brenden Aaronson applied a cool finish with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had been held by struggling Wolves at Old Trafford earlier in the week.
However, against a team who had two days less to recover, Cunha restored parity three minutes later when he ran on to a pass from introduced the Dutchman and slid a finish underneath rushing Leeds 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 Amorim is without several key attacking players due to a combination of fitness issues and international duty.
Not that the hosts to care about that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven games, their longest such streak since 2001, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's options.
It's not that the absent players are the answer 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 have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost instantly after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds Analysis: Another Step Towards Survival
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of expected fervor, but the hostile edge was not as pronounced as in previous fixtures.
The home fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin 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 defensive error opened the door for the opener.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a wider context for the manager and the club to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's position.
Instead, he is now masterminding significant improvement.
The task is not done yet but step by step, 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 domestic cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also entering their cup journey with a home tie.
