Key Moments
- Dominic Calvert-Lewin watches a early header come back off the post.
- Aaronson fires the home side ahead with a low finish in the second half.
- Matheus Cunha responds just three minutes later.
- The Yorkshire side continue their longest top-flight undefeated streak since the turn of the century.
The Red Devils' disappointing run of form continued at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for the team not suffering even more damage against their old rivals.
The Everton loanee headed a first-half effort against the post for the in-form hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had less time to prepare, the forward levelled three minutes after the opener when he latched onto a pass from substitute Joshua Zirkzee and guided a shot underneath rushing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his big-money summer move and came at a time when the manager is without several key attacking players due to a combination of fitness issues and international duty.
Not that Leeds to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular 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 close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven matches, their best such streak since 2001, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a swift exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team's options.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, the boss has few attacking options.
He evidently does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided 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 playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds Analysis: Another Step Towards Safety
After memorable victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of expected fervor, but the hostile edge was not as pronounced as in previous encounters.
Leeds' 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 rare moment of quality in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context for the manager and Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now overseeing clear progress.
The task is not done yet but step by step, Leeds are getting nearer to securing their top-flight status.
Looking Ahead
Leeds have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also entering their FA Cup journey with a home tie.
