Match Summary
- Dominic Calvert-Lewin watches a first-half header ricochet off the post.
- Aaronson puts the hosts ahead with a well-placed strike in the second period.
- Cunha responds only three minutes later.
- The Yorkshire side extend their best top-flight undefeated streak since the turn of the century.
Manchester United's poor run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more disappointment against their old rivals.
The Everton loanee directed a first-half attempt against the woodwork for the in-form hosts before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
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 restored parity three minutes later when he ran on to a pass from substitute Joshua Zirkzee and guided a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth 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 Leeds 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 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 close range.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The draw prolongs the home side's unbeaten run to seven games, their longest such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Existing 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 missing pair are the answer to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the assist for the equaliser almost immediately after his introduction as a substitute.
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 showing, the big-money frontman looks similar to 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 young striker.
Leeds Analysis: Another Step Towards Survival
After memorable victories in their last few home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of expected atmosphere, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more preoccupied about their side's inability to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for Daniel Farke and the club to deal with.
When they endured a poor run of form earlier in the campaign, many speculated about the manager's future.
In contrast, he is now masterminding significant improvement.
The task is not completed yet but gradually, Leeds are getting closer to achieving their top-flight status.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
