At a Glance
- Dominic Calvert-Lewin watches a early header come back off the post.
- Brenden Aaronson puts the hosts ahead with a well-placed effort in the second period.
- Cunha levels just three minutes later.
- The Yorkshire side extend their best top-flight unbeaten run since the turn of the century.
Manchester United's disappointing recent struggles persisted at Leeds' fortress, but manager Ruben Amorim had his Brazilian forward to thank for his side avoiding even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-half attempt against the post for the in-form hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had less time to prepare, Cunha restored parity three minutes after the opener when he ran on to a pass from substitute the Dutchman and slid a finish underneath rushing home 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 Amorim is without several key attacking players due to a mix of injury and international duty.
Not that Leeds to sympathise with that given their own tight schedule.
The Swiss attacker forced a full length 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 impression, turned his teammate's cut-back wide from six yards out.
Cunha, 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 games, their best such streak since 2001, and takes them a significant margin clear of the drop zone.
For the visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, the United coach could be forgiven for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other attackers is having on the team's squad.
It's not that the missing pair are the solution 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 attacking options.
He evidently does not trust youngster Shea Lacey or the seasoned Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their natural positions, alongside Benjamin Sesko.
On this evidence, the big-money frontman looks similar to previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Survival
After memorable victories in their previous home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were moments of expected fervor, but the hostile edge was not as evident as in other encounters.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an rare moment of quality in a congested 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, The home 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 poor run of form earlier in the campaign, many thought about the manager's position.
Instead, he is now masterminding significant improvement.
The task is not completed yet but gradually, the team are getting nearer to achieving their top-flight status.
What Happens Next?
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also entering their cup journey with a Old Trafford tie.
