Match Summary
- Dominic Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson puts the hosts ahead with a well-placed effort in the second half.
- Matheus Cunha levels only three minutes later.
- The Yorkshire side extend their best Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but manager the Portuguese tactician had Matheus Cunha to thank for the team not suffering even more disappointment against Leeds.
The Everton loanee headed a first-period effort against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a driven, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had less time to recover, Cunha restored parity three minutes later when he latched onto a pass from introduced the Dutchman and guided a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money summer move and came at a time when the manager is without four key attacking players due to a mix of fitness issues and international duty.
Not that Leeds to care about that given their own lack of preparation time.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also blasted against a post late on.
The point extends Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, squandered.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its knockout phase, Amorim could be understood for hoping the participating nations make a swift exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other attackers is having on Amorim's options.
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 suffered disappointing results earlier in the season.
But without them, the boss has few attacking options.
He clearly does not have full faith in youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost immediately after his arrival as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of typical fervor, but the intimidating edge was not as evident as in previous encounters.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in dangerous 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 defensive error opened the door for the opener.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager and the club to deal with.
When they suffered a poor run of form earlier in the season, many speculated about the manager's position.
Instead, he is now overseeing clear improvement.
The job is not done yet but gradually, Leeds are getting nearer to securing their survival.
Looking Ahead
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also beginning their FA Cup journey with a home tie.
