At a Glance
- Calvert-Lewin watches a early header ricochet off the post.
- Aaronson fires the hosts ahead with a low finish in the second period.
- Cunha levels only three minutes afterwards.
- The Yorkshire side continue their best Premier League unbeaten run since the turn of the century.
The Red Devils' poor run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin directed a first-half effort against the woodwork for the confident home team before Brenden Aaronson finished superbly with a driven, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to recover, Cunha levelled three minutes later when he latched onto a pass from substitute the Dutchman 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 combination of injury and national team commitments.
Not that you would expect Leeds to care about that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned his teammate's cut-back wide from close range.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also fired against a post late on.
The draw prolongs the home side's unbeaten run to seven matches, their best such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the Manchester United though, it was yet another opportunity to move into fourth spot, albeit only for a short time, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the participating nations make a swift exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability of other attackers is having on the team's options.
It's not that the missing pair are the answer 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, the boss has limited attacking options.
He clearly does not trust youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward provided the assist for Cunha's equaliser almost instantly 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 Sesko.
On this evidence, the big-money frontman looks no better than previous struggling signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Survival
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 expected atmosphere, but the hostile edge was not as evident as in other encounters.
Leeds' fans were more preoccupied about their side's inability to get worthwhile 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 tight first half.
It still felt as though Leeds were struggling when a defensive error opened the door for the opener.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
However, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a difficult run of form earlier in the season, many thought about the manager's future.
Instead, he is now masterminding clear progress.
The job is not done yet but gradually, Leeds are getting nearer to achieving their top-flight status.
What Happens Next?
Leeds 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 Premier League trip to Burnley before also beginning their FA Cup journey with a Old Trafford tie.
