Key Moments
- Dominic Calvert-Lewin watches a first-half header come back off the upright.
- Brenden Aaronson puts the hosts ahead with a well-placed effort in the second period.
- Cunha responds only three minutes later.
- Leeds continue their best top-flight unbeaten run since 2001.
Manchester United's poor run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the woodwork for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
At that stage, the United boss 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 a team 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 introduced the Dutchman and guided a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and international duty.
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 visiting goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also fired against a post late on.
The draw extends 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 chance to move into fourth spot, albeit only for a short time, squandered.
Manchester United Breakdown: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on the team's squad.
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 suffered poor results earlier in the season.
But without them, Amorim has few attacking options.
He evidently does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the assist for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and conviction in front of goal.
Sesko's 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 memorable victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were instances of typical atmosphere, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any length of time.
The striker's header that clipped the post was an isolated moment of threat in a tight first half.
It still felt as though the hosts were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a difficult run of form earlier in the season, many thought about the manager's position.
Instead, he is now overseeing significant progress.
The task is not done yet but step by step, the team are getting nearer to securing their top-flight status.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also entering their FA Cup journey with a Old Trafford tie.
