Key Moments
- Dominic Calvert-Lewin sees a early header come back off the post.
- Aaronson puts the home side ahead with a well-placed strike in the second half.
- Cunha responds only three minutes later.
- Leeds continue their best top-flight unbeaten run since 2001.
The Red Devils' poor run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more disappointment against Leeds.
The Everton loanee headed a first-half effort against the woodwork for the in-form home team before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to prepare, Cunha levelled three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and slid a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian'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 injury and international duty.
Not that the hosts to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also blasted against a post late on.
The draw prolongs Leeds' unbeaten run to seven games, their longest 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 matter of hours, wasted.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's squad.
It's not that the absent players are the answer to all of United's problems. After all, they were part of the side that experienced poor results earlier in the season.
But without them, the boss has few attacking options.
He clearly does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home Zirkzee's 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 previous home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of expected fervor, but the intimidating edge was not as evident as in other encounters.
The home fans were more preoccupied about their side's inability to get worthwhile possession in advanced areas for any length of time.
The striker's header that struck the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for the opener.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many speculated about the manager's future.
In contrast, he is now masterminding significant progress.
The job is not done yet but gradually, Leeds are getting closer to securing their survival.
Looking Ahead
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
