Match Summary
Manchester United's disappointing run of form persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
The Everton loanee directed a first-half attempt against the post for the in-form home team before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had been held by bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to prepare, the forward restored parity three minutes after the opener when he ran on to a through ball from substitute the Dutchman and guided a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League 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 national team commitments.
Not that the hosts to care about that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impression, turned Zirkzee's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the contest, also blasted against a post in the dying moments.
The draw prolongs Leeds' unbeaten run to seven matches, their longest such streak since 2001, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, wasted.
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the absence of other attackers is having on Amorim's options.
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 disappointing results earlier in the campaign.
But without them, Amorim has few attacking options.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the assist for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Sesko.
On this evidence, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a comparatively subdued affair.
True, there were instances of typical fervor, but the hostile edge was not as pronounced as in other fixtures.
Leeds' fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The striker's header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now overseeing clear improvement.
The task is not completed yet but step by step, the team are getting closer to securing their survival.
The Yorkshire club have a Premier League trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also entering their cup journey with a home tie.
