Key Moments
- Dominic Calvert-Lewin watches a first-half header come back off the post.
- Aaronson fires the home side ahead with a low finish in the second period.
- Matheus Cunha responds just three minutes afterwards.
- The Yorkshire side extend their best Premier League unbeaten run since the turn of the century.
The Red Devils' poor run of form persisted at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for the team avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the confident home team before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
At that stage, the United boss was in the firing line after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
However, against a team who had less time to recover, 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 Leeds 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 Amorim is without four key attacking players due to a combination of fitness issues and international duty.
Not that Leeds to sympathise with that given their own lack of preparation time.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post in the dying moments.
The point prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, wasted.
Man Utd Analysis: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards 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 experienced poor results earlier in the season.
But without them, Amorim has limited attacking options.
He clearly does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the assist for Cunha's equaliser almost instantly after his arrival as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this showing, the expensive 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 Analysis: A Further Step Towards Safety
After memorable victories in their last few home games, the arrival of their biggest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of expected fervor, but the intimidating edge was not as evident as in previous fixtures.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The striker's header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were struggling when a defensive error 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 wider context for the manager and the club to deal with.
When they suffered a poor run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now overseeing significant improvement.
The task is not done yet but gradually, the team are getting nearer to achieving their top-flight status.
What Happens Next?
The Yorkshire club 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 Premier League trip to Turf Moor before also entering their FA Cup journey with a Old Trafford tie.
