Key Moments
- Dominic Calvert-Lewin sees a early header come back off the upright.
- Aaronson puts the hosts ahead with a low effort in the second half.
- Cunha levels only three minutes later.
- The Yorkshire side continue their best top-flight unbeaten run since the turn of the century.
Manchester United's disappointing run of form persisted at Leeds' fortress, but head coach Ruben Amorim had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
The Everton loanee headed a first-half effort against the woodwork for the confident hosts before Brenden Aaronson finished superbly with a low, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
Nevertheless, against a team who had two days less to prepare, the forward levelled three minutes later when he latched onto a through ball from introduced Joshua Zirkzee and slid a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his big-money 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 Leeds to care about 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 United heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the match, also blasted against a post in the dying moments.
The draw 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 fourth spot, albeit only for a matter of hours, wasted.
Manchester United Breakdown: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team's options.
It's not that the missing pair are the solution 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, the boss 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 Dutch forward provided the assist for the equaliser almost immediately after his introduction as a substitute.
That leaves the Brazilian, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks similar to previous underwhelming signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Survival
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 expected atmosphere, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any length of time.
The striker's header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were struggling when a defensive error opened the door for Aaronson.
For a short moment, Leeds' ecstatic fans thought they were about to secure a rare win against Manchester United.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they endured a poor run of form earlier in the season, many thought about the manager's position.
In contrast, he is now overseeing significant improvement.
The task is not completed yet but step by step, Leeds are getting closer to securing their survival.
Looking Ahead
Leeds have a top-flight trip to Newcastle 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.
