Match Summary
- Dominic Calvert-Lewin watches a first-half header ricochet off the upright.
- Aaronson fires the hosts ahead with a low effort in the second half.
- Cunha levels only three minutes afterwards.
- The Yorkshire side continue their best Premier League undefeated streak since 2001.
The Red Devils' poor recent struggles persisted at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the confident home team before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had less time to recover, Cunha restored parity three minutes later when he latched onto a pass from substitute the Dutchman and guided a shot underneath advancing 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 combination of injury and international duty.
Not that you would expect Leeds to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impression, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team's squad.
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 youngster Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost instantly after his arrival 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 no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Survival
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 moments of typical atmosphere, but the intimidating edge was not as evident as in other encounters.
The home fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an rare moment of threat in a tight first half.
It still felt as though Leeds were finding it tough when a defensive error 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.
However, there is a wider context for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now overseeing significant progress.
The job is not completed yet but gradually, Leeds are getting nearer to achieving their survival.
What Happens Next?
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their cup journey with a Old Trafford tie.
