Match Summary
- Calvert-Lewin sees a first-half header ricochet off the upright.
- Aaronson fires the hosts ahead with a well-placed effort in the second period.
- Cunha equalises only three minutes later.
- The Yorkshire side extend their best Premier League unbeaten run since 2001.
The Red Devils' poor recent struggles persisted at Elland Road, but manager the Portuguese tactician had Matheus Cunha to thank for his side avoiding even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had two days less to recover, the forward levelled three minutes after the opener when he ran on to a pass from introduced Joshua Zirkzee and guided a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without four key attacking players due to a combination of injury and international duty.
Not that you would expect 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 visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The draw prolongs the home side's unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards 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 experienced disappointing results earlier in the season.
But without them, Amorim has few alternatives in attack.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their natural positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.

Leeds' fans were more concerned about their side's struggle to get sustained possession in dangerous areas for any length of time.
