Match Summary
Manchester United's disappointing run of form continued at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for the team not suffering even more disappointment against Leeds.
The Everton loanee headed a first-half attempt against the woodwork for the confident home team before the American midfielder applied a cool finish with a low, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had been held by struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had less time to recover, Cunha restored parity three minutes later when he ran on to a through ball from substitute Joshua Zirkzee and guided a shot underneath advancing home 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 four key attacking players due to a mix of injury and international duty.
Not that you would expect the hosts to sympathise with that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a audacious 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 close range.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The draw extends Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, wasted.
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 absence of other attackers is having on the team's options.
It's not that the missing pair are the answer 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 limited attacking options.
He evidently does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence and assurance 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.
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as evident as in other fixtures.
The home fans were more concerned about their side's inability to get sustained possession in advanced areas for any prolonged period.
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 struggling when a defensive error opened the door for Aaronson.
For a short moment, Leeds' ecstatic 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 the club to deal with.
When they endured a poor run of form earlier in the season, many speculated about the manager's position.
In contrast, he is now overseeing clear progress.
The job is not completed yet but step by step, Leeds are getting closer to securing their top-flight status.
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also entering their cup journey with a home tie.
