Match Summary
- Calvert-Lewin sees a early header come back off the post.
- Aaronson puts the home side ahead with a well-placed effort in the second half.
- Matheus Cunha equalises just three minutes afterwards.
- Leeds continue their longest Premier League undefeated streak since 2001.
Manchester United's disappointing recent struggles continued at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
Dominic Calvert-Lewin headed a first-half effort against the woodwork for the confident hosts before the American midfielder finished superbly with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to prepare, Cunha levelled three minutes after the opener when he ran on to a through ball from substitute Joshua Zirkzee and slid a shot underneath advancing home goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when the manager is without several key attacking players due to a mix of injury and international duty.
Not that the hosts to care about that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, who is struggling to make an impact, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post in the dying moments.
The draw extends Leeds' unbeaten run to seven games, their best such streak since 2001, and takes them a significant margin 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.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, Amorim 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 Amorim's options.
It's not that the absent players are the answer to all of United's problems. After all, they were part of the side that suffered disappointing results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He evidently does not have full faith in 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 introduction as a substitute.
That leaves Cunha, who has now scored a small tally in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as pronounced as in other encounters.
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 Leeds were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for Daniel Farke and the club to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's position.
In contrast, he is now overseeing clear improvement.
The job is not done yet but gradually, the team are getting nearer to achieving their top-flight status.
Looking Ahead
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
