At a Glance
- Calvert-Lewin watches a first-half header ricochet off the post.
- Aaronson puts the home side ahead with a low finish in the second period.
- Matheus Cunha responds just three minutes afterwards.
- The Yorkshire side continue their best Premier League undefeated streak since the turn of the century.
Manchester United's disappointing run of form continued at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post for the confident home team before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had failed to beat 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 after the opener when he ran on to a pass from substitute the Dutchman and slid a finish underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a combination of injury and national team commitments.
Not that the hosts to care about that given their own tight schedule.
Noah Okafor 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 impression, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The point extends the home side's unbeaten run to seven matches, their best 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 chance to move into fourth spot, albeit only for a matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the absence of other attackers is having on Amorim's options.
It's not that the missing pair are the solution 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 alternatives in attack.
He clearly does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost immediately after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and conviction in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the new signing.
