At a Glance
- Dominic Calvert-Lewin watches a early header come back off the upright.
- Aaronson fires the hosts ahead with a well-placed effort in the second period.
- Cunha levels only three minutes afterwards.
- The Yorkshire side extend their best Premier League unbeaten run since the turn of the century.
Manchester United's poor recent struggles continued at Leeds' fortress, but head coach the Portuguese tactician had Matheus Cunha to thank for the team avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-period effort against the woodwork for the confident hosts before the American midfielder 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 Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha restored parity three minutes later when he latched onto a through ball from substitute the Dutchman and slid a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a mix of injury and international duty.
Not that the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of visiting 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 his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired 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 relegation zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a short time, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the AFCON reaching its latter stages, Amorim could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other forwards is having on Amorim's squad.
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 suffered poor results earlier in the season.
But without them, the boss has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others playing out of their natural positions, alongside Benjamin Sesko.
On this evidence, the expensive frontman looks no better than previous struggling 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: Another 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 instances of typical atmosphere, but the hostile edge was not as evident as in other fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in advanced areas for any length of time.
The striker's header that clipped the post was an isolated moment of quality in a congested first half.
It still felt as though the hosts were struggling when a defensive error opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a coveted win against their old foes.
However, there is a much bigger picture for Daniel Farke 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 clear progress.
The task is not done yet but step by step, Leeds are getting closer to securing their survival.
Looking Ahead
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. Manchester United face a league trip to Turf Moor before also entering their cup journey with a home tie.
