Match Summary
Manchester United's disappointing recent struggles continued at Elland Road, but head coach Ruben Amorim had Matheus Cunha to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-period attempt against the post for the in-form home team before the American midfielder finished superbly with a low, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at Old Trafford earlier in the week.
However, against a team who had less time to prepare, Cunha restored parity three minutes later when he ran on to a pass from substitute Joshua Zirkzee and slid a finish 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 fitness issues and international duty.
Not that the hosts to sympathise with that given their own lack of preparation time.
Noah Okafor forced a diving 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 impact, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The point prolongs Leeds' unbeaten run to seven games, their longest such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, wasted.
With the AFCON reaching its knockout phase, the United coach could be understood for hoping the participating nations 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 missing pair are the answer to all of United's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, Amorim has limited attacking options.
He evidently does not trust youngster 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 replacement.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in confidence and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
After memorable victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were moments of expected atmosphere, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any length of time.
The Calvert-Lewin header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, 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 speculated about the manager's future.
Instead, he is now overseeing significant progress.
The job is not done yet but gradually, Leeds are getting closer to securing their survival.
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
