Match Summary
Manchester United's disappointing run of form continued at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against Leeds.
The Everton loanee headed a first-half effort against the post for the confident home team before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had been held by struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to recover, the forward levelled three minutes after the opener when he ran on to a pass from substitute 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 high-profile summer move and came at a time when the manager is without four key attacking players due to a mix of fitness issues and national team commitments.
Not that Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, 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 in the dying moments.
The point prolongs the home side's unbeaten run to seven matches, their best such streak since over two decades ago, 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 short time, squandered.
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other attackers is having on the team'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 suffered poor results earlier in the season.
But without them, Amorim has few attacking options.
He evidently does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost immediately after his arrival 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 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 young striker.
After memorable victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as evident 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 struck the post was an rare moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context for Daniel Farke 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 overseeing clear improvement.
The task is not done yet but step by step, Leeds are getting closer to achieving their survival.
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also entering their FA Cup journey with a home tie.
