Key Moments
- Dominic Calvert-Lewin sees a early header come back off the upright.
- Aaronson fires the home side ahead with a well-placed effort in the second half.
- Matheus Cunha levels only three minutes later.
- Leeds extend their longest top-flight unbeaten run since the turn of the century.
The Red Devils' disappointing recent struggles continued at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against Leeds.
The Everton loanee headed a first-period attempt against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
With the goal, the United boss was in the firing line after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had less time to recover, the forward levelled three minutes later when he latched onto 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 Premier League goal since his big-money summer move and came at a time when Amorim is without several key attacking players due to a combination of fitness issues and national team commitments.
Not that the hosts to sympathise with 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 Zirkzee'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 prolongs Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, squandered.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other attackers 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 suffered disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost immediately after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks no better than previous struggling signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as evident as in other fixtures.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The striker's header that clipped the post was an rare moment of threat in a congested first half.
It still felt as though the hosts were struggling when a mistake opened the door for the opener.
Ever so briefly, The home delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a wider context 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 future.
In contrast, he is now masterminding clear progress.
The job is not done yet but gradually, the team are getting closer to securing their survival.
