At a Glance
- Calvert-Lewin watches a first-half header come back off the upright.
- Aaronson fires the hosts ahead with a low strike in the second half.
- Matheus Cunha responds just three minutes later.
- The Yorkshire side extend their best Premier League unbeaten run since 2001.
The Red Devils' poor run of form continued at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
Dominic Calvert-Lewin directed a first-period attempt against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute shot.
With the goal, 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 later when he latched onto a pass from introduced the Dutchman and guided a shot underneath rushing home 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 several 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 spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is finding it hard 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 contest, also blasted against a post in the dying moments.
The draw extends Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, wasted.
Man Utd Analysis: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to captain Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other forwards is having on the team's squad.
It's not that the absent players 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 limited alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward delivered the assist for Cunha's equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside Sesko.
On this evidence, the expensive frontman looks similar to previous underwhelming signings, lacking in confidence and conviction in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds Analysis: A Further Step Towards Safety
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 expected atmosphere, but the hostile edge was not as evident as in previous fixtures.
The home fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an rare moment of threat in a tight first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a much bigger picture for the manager and Leeds to deal with.
When they endured a poor run of form earlier in the campaign, many speculated about the manager's future.
Instead, he is now masterminding significant improvement.
The task is not completed yet but gradually, the team are getting nearer to securing their top-flight status.
Looking Ahead
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a Premier League trip to Burnley before also entering their cup journey with a home tie.
