Match Summary
- Dominic Calvert-Lewin sees a first-half header come back off the upright.
- Aaronson fires the hosts ahead with a well-placed finish in the second half.
- Cunha levels just three minutes afterwards.
- The Yorkshire side extend their best Premier League unbeaten run since the turn of the century.
Manchester United's disappointing run of form continued at Leeds' fortress, but head coach Ruben Amorim had Matheus Cunha to thank for his side not suffering even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the in-form home team before the American midfielder finished superbly with a driven, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had less time to prepare, Cunha levelled three minutes after the opener when he latched onto a pass from introduced the Dutchman and guided a shot underneath rushing home 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 injury and international duty.
Not that the hosts to care about that given their own tight schedule.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when Benjamin Sesko, who is struggling 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 late on.
The draw extends 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 the Champions League places, albeit only for a matter of hours, squandered.
Man Utd Analysis: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence 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 poor results earlier in the season.
But without them, Amorim has limited alternatives in attack.
He clearly does not trust youngster Shea Lacey or the much more experienced Zirkzee, even though the Dutch forward provided the through ball for the equaliser almost immediately after his introduction as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous underwhelming signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
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 atmosphere, but the hostile edge was not as evident as in other fixtures.
The home fans were more concerned about their side's struggle to get sustained possession in dangerous areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, 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 Leeds 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 masterminding clear progress.
The task is not done yet but gradually, the team are getting nearer to securing their survival.
What Happens Next?
The Yorkshire club have a Premier League 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 FA Cup journey with a home tie.
