Match Summary
- Calvert-Lewin watches a first-half header ricochet off the upright.
- Brenden Aaronson puts the home side ahead with a well-placed strike in the second period.
- Cunha equalises just three minutes afterwards.
- Leeds continue their best Premier League undefeated streak since 2001.
Manchester United's poor recent struggles persisted at Leeds' fortress, but manager 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-half attempt against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a driven, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward restored parity three minutes after the opener when he ran on to a through ball from substitute the Dutchman and guided a shot underneath advancing 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 Amorim is without four key attacking players due to a mix of injury and national team commitments.
Not that you would expect the hosts to care about that given their own tight schedule.
Noah Okafor 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 finding it hard to make an impression, 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 point extends the home side's unbeaten run to seven games, their longest 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 opportunity to move into the Champions League places, albeit only for a short time, wasted.
Man Utd Analysis: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's options.
It's not that the absent players are the solution to all of United'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 evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the through ball for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Sesko.
On this evidence, 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.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as pronounced as in previous fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The striker's header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for the opener.
For a short moment, The home ecstatic fans thought they were about to secure a rare win against their old foes.
Nevertheless, 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 season, many thought about the manager's position.
In contrast, he is now masterminding significant improvement.
The job is not completed yet but gradually, Leeds are getting nearer to achieving their survival.
Looking Ahead
Leeds have a top-flight 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 entering their FA Cup journey with a Old Trafford tie.
