Match Summary
- Dominic Calvert-Lewin sees a first-half header ricochet off the post.
- Aaronson fires the home side ahead with a well-placed finish in the second period.
- Matheus Cunha levels just three minutes afterwards.
- The Yorkshire side continue their longest top-flight undefeated streak since the turn of the century.
The Red Devils' disappointing run of form persisted at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-half effort against the post for the in-form home team before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against a team who had two days less to prepare, Cunha levelled three minutes later when he latched onto a through ball from introduced Joshua Zirkzee and slid a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth 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 injury and international duty.
Not that the hosts to care about that given their own tight schedule.
The Swiss attacker 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 struggling to make an impact, 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 blasted against a post late on.
The draw prolongs Leeds' unbeaten run to seven games, their best such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, squandered.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, the United coach could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on Amorim's squad.
It's not that the missing pair are the answer to all of the club'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 alternatives in attack.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous struggling signings, lacking in confidence and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Safety
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of expected atmosphere, but the hostile edge was not as evident as in other encounters.
The home fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an rare moment of quality in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
For a short moment, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
Nevertheless, there is a much bigger picture 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 future.
Instead, he is now masterminding clear progress.
The job is not done yet but gradually, the team are getting closer to achieving their survival.
Looking Ahead
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 league trip to Burnley before also beginning their cup journey with a Old Trafford tie.
