At a Glance
- Dominic Calvert-Lewin sees a early header ricochet off the upright.
- Aaronson fires the home side ahead with a well-placed finish in the second period.
- Matheus Cunha equalises only three minutes afterwards.
- Leeds extend their best 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 Leeds.
Dominic Calvert-Lewin directed a first-period attempt against the woodwork for the in-form hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute effort.
With the goal, the United boss was in the firing line after his side had failed to beat bottom-of-the-table Wolves at home earlier in the week.
Nevertheless, against opponents who had less time to prepare, Cunha restored parity three minutes later when he ran on to a through ball from substitute the Dutchman and guided a finish underneath rushing Leeds 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 several key attacking players due to a mix of fitness issues and international duty.
Not that you would expect Leeds to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impact, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also fired against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's options.
It's not that the absent players are the answer to all of the club's problems. After all, they were part of the side that suffered disappointing results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost immediately after his arrival as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds Analysis: Another Step Towards Safety
After thrilling victories in their last few home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of typical fervor, but the hostile edge was not as evident as in other encounters.
Leeds' fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The Calvert-Lewin header that clipped the post was an rare moment of quality in a tight first half.
It still felt as though Leeds were finding it tough when a mistake opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
However, there is a wider context for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's future.
In contrast, he is now overseeing clear progress.
The task is not done yet but step by step, the team are getting nearer to securing their survival.
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. The Red Devils face a league trip to Turf Moor before also beginning their cup journey with a Old Trafford tie.
