Key Moments
- Calvert-Lewin sees a early header ricochet off the upright.
- Brenden Aaronson puts the home side ahead with a well-placed finish in the second period.
- Cunha equalises just three minutes later.
- The Yorkshire side continue their best Premier League unbeaten run since 2001.
Manchester United's poor run of form persisted at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more damage against their old rivals.
The Everton loanee headed a first-half effort against the woodwork for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
At that stage, the United boss was under intense scrutiny after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against a team who had two days less to recover, the forward restored parity three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and guided a finish underneath rushing 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 several key attacking players due to a mix of fitness issues and national team commitments.
Not that the hosts to sympathise with 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 United heads were in hands when the Slovenian striker, who is struggling to make an impact, 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 eight points 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, squandered.
Man Utd Analysis: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Existing 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 missing pair are the answer to all of the club's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, the boss has limited alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward provided the assist for Cunha's equaliser almost immediately after his arrival as a replacement.
That leaves the Brazilian, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous underwhelming signings, lacking in belief and conviction in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
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 moments of typical fervor, but the hostile edge was not as evident as in previous encounters.
The home fans were more preoccupied about their side's struggle to get sustained possession in advanced areas for any prolonged period.

For a short moment, The home ecstatic fans thought they were about to secure a coveted win against their old foes.
However, there is a much bigger picture for Daniel Farke and Leeds to deal with.

The task is not completed yet but gradually, Leeds are getting closer to achieving their top-flight status.
