Key Moments
- Calvert-Lewin sees a early header ricochet off the post.
- Brenden Aaronson puts the hosts ahead with a well-placed strike in the second half.
- Matheus Cunha levels just three minutes later.
- The Yorkshire side continue their best Premier League unbeaten run since the turn of the century.
Manchester United's disappointing recent struggles persisted at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-period effort against the woodwork for the confident home team before the American midfielder finished superbly with a low, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
However, against opponents who had less time to recover, the forward levelled three minutes later when he latched onto a pass from introduced Joshua Zirkzee and guided a finish 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 the manager is without several key attacking players due to a combination of fitness issues and national team commitments.
Not that the hosts to care about that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post late on.
The draw extends Leeds' unbeaten run to seven matches, their best such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Struggle Again
With the AFCON reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other attackers 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 disappointing results earlier in the season.
But without them, Amorim has limited alternatives in attack.
He evidently does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the assist for Cunha's equaliser almost immediately after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous underwhelming signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
