At a Glance
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Aaronson puts the hosts ahead with a well-placed strike in the second half.
- Matheus Cunha responds only three minutes afterwards.
- Leeds continue their longest Premier League unbeaten run since 2001.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more disappointment against Leeds.
The Everton loanee directed a first-half effort against the woodwork for the confident hosts before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, the United boss was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
However, against opponents who had less time to recover, the forward restored parity three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and slid a finish underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a combination of fitness issues and international duty.
Not that you would expect the hosts to care about that given their own tight schedule.
Noah Okafor 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 struggling to make an impression, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The point 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 visitors 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 AFCON reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star 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 the club's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He clearly does not trust youngster Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous struggling signings, lacking in belief 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 young striker.
Leeds United Breakdown: Another Step Towards Safety
After thrilling victories in their last few home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were moments of typical atmosphere, but the hostile edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's inability to get worthwhile possession in dangerous areas for any length of time.
The Calvert-Lewin header that struck the post was an rare moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' ecstatic fans thought they were about to secure a rare win against Manchester United.
However, there is a much bigger picture 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 position.
Instead, he is now overseeing clear improvement.
The job is not done yet but gradually, the team are getting closer to achieving their survival.
What Happens Next?
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Turf Moor before also entering their cup journey with a home tie.
