Match Summary
- Dominic Calvert-Lewin watches a early header ricochet off the upright.
- Aaronson puts the hosts ahead with a well-placed effort in the second period.
- Matheus Cunha equalises only three minutes later.
- The Yorkshire side extend their best Premier League undefeated streak since 2001.
Manchester United's disappointing run of form continued at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
The Everton loanee directed a first-period attempt against the woodwork for the in-form hosts before the American midfielder finished superbly with a driven, 62nd-minute effort.
With the goal, the United boss was under intense scrutiny after his side had been held by struggling Wolves at home earlier in the week.
However, against a team who had two days less to recover, Cunha levelled three minutes after the opener when he ran on to a pass from introduced Joshua Zirkzee and guided a finish underneath rushing 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 combination of fitness issues and national team commitments.
Not that you would expect the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the match, also fired 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 eight points clear of the relegation zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on the team's squad.
It's not that the missing pair are the solution to all of United's problems. After all, they were part of the side that experienced disappointing results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He evidently does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost immediately 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 showing, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their last few home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of typical fervor, but the intimidating edge was not as evident as in other encounters.
The home fans were more concerned about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The striker's header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were struggling when a defensive error opened the door for the opener.
For a short moment, Leeds' ecstatic fans thought they were about to secure a rare win against their old foes.
However, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now masterminding clear progress.
The job is not completed yet but step by step, the team are getting nearer to securing their survival.
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 beginning their FA Cup journey with a Old Trafford tie.
