At a Glance
- Calvert-Lewin sees a first-half header come back off the post.
- Brenden Aaronson fires the hosts ahead with a well-placed strike in the second period.
- Cunha levels just three minutes later.
- The Yorkshire side continue their longest top-flight undefeated streak since 2001.
Manchester United's disappointing run of form continued 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.
The Everton loanee directed a first-period effort against the post for the confident hosts before the American midfielder finished superbly with a driven, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against opponents who had two days less to prepare, Cunha restored parity three minutes later when he ran on to a through ball from introduced the Dutchman and slid a shot underneath rushing home goalkeeper Lucas Perri.
It was only the South American'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 mix of fitness issues and international duty.
Not that you would expect the hosts to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The point prolongs the home side's unbeaten run to seven games, their longest such streak since 2001, 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 short time, wasted.
Manchester United Breakdown: The Manager's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a swift exit.
Current injuries to captain 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 absent players 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 campaign.
But without them, the boss has limited alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks no better than previous struggling signings, lacking in confidence 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.

After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
