At a Glance
Manchester United's disappointing recent struggles continued at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
The Everton loanee directed a first-period effort against the woodwork for the in-form hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had been held by struggling Wolves at Old Trafford earlier in the week.
However, against opponents who had less time to prepare, Cunha restored parity three minutes later when he ran on to a pass from introduced the Dutchman and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his big-money 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 Leeds to sympathise with that given their own tight schedule.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impact, turned his teammate's cut-back wide from close range.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The point prolongs the home side's unbeaten run to seven games, their best such streak since over two decades ago, and takes them eight points clear of the drop zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
With the AFCON reaching its latter stages, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the unavailability 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 suffered poor results earlier in the season.
But without them, the boss has limited alternatives in attack.
He evidently does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward provided the through ball for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their preferred positions, alongside Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in confidence 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.
After memorable victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of typical atmosphere, but the hostile edge was not as evident as in previous encounters.
Leeds' fans were more concerned about their side's struggle to get sustained possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts 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 the club to deal with.
When they endured a difficult run of form earlier in the campaign, many thought about the manager's future.
In contrast, he is now overseeing clear improvement.
The job is not done yet but gradually, Leeds are getting closer to achieving their top-flight status.
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Turf Moor before also beginning their cup journey with a Old Trafford tie.
