Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the post.
- Aaronson fires the hosts ahead with a well-placed finish in the second half.
- Matheus Cunha equalises just three minutes afterwards.
- The Yorkshire side continue their best Premier League undefeated streak since 2001.
Manchester United's poor run of form persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
The Everton loanee headed a first-period attempt against the post for the in-form hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had less time to prepare, the forward restored parity three minutes after the opener when he latched onto a through ball from introduced the Dutchman and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a combination of fitness issues and international duty.
Not that the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned his teammate's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also blasted 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 a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, squandered.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on Amorim's squad.
It's not that the absent players are the solution 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, the boss 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 Netherlands forward provided the assist for Cunha's equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of typical fervor, but the hostile 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 striker's header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for the opener.
Ever so briefly, 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 suffered a poor 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 step by step, Leeds are getting nearer to achieving their top-flight status.
What Happens Next?
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 Turf Moor before also beginning their cup journey with a Old Trafford tie.
