At a Glance
- Dominic Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson puts the hosts ahead with a well-placed finish in the second period.
- Cunha levels just three minutes afterwards.
- The Yorkshire side continue their best Premier League unbeaten run since the turn of the century.
Manchester United's poor run of form continued at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against Leeds.
The Everton loanee headed a first-half effort against the post for the confident home team before Brenden Aaronson finished superbly with a driven, 62nd-minute effort.
At that stage, the United boss was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had two days less to prepare, Cunha restored parity three minutes after the opener when he latched onto a pass from substitute Joshua Zirkzee and slid a shot underneath rushing home 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 Amorim is without four key attacking players due to a mix of injury and international duty.
Not that Leeds to care about 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 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.
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 matches, their best such streak since 2001, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other attackers is having on Amorim's squad.
It's not that the missing pair are the solution to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in confidence and conviction in front of goal.
Sesko's failure to turn home the 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 home was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more preoccupied about their side's struggle 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 Leeds were finding it tough when a mistake opened the door for Aaronson.
For a short moment, Leeds' 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 campaign, many thought about the manager's future.
In contrast, he is now overseeing clear improvement.
The task is not done yet but gradually, Leeds are getting closer to securing their top-flight status.
What Happens Next?
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also beginning their FA Cup journey with a home tie.
