At a Glance
- Calvert-Lewin sees a early header ricochet off the post.
- Brenden Aaronson puts the hosts ahead with a low finish in the second period.
- Cunha levels only three minutes afterwards.
- The Yorkshire side extend their longest top-flight unbeaten run since the turn of the century.
The Red Devils' poor recent struggles persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more disappointment against Leeds.
Dominic Calvert-Lewin directed a first-period attempt against the woodwork for the confident hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against a team who had less time to recover, Cunha restored parity three minutes later when he latched onto a through ball from introduced the Dutchman and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian'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 injury and national team commitments.
Not that you would expect the hosts to care about that given their own lack of preparation time.
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 Benjamin Sesko, who is finding it hard to make an impression, turned his teammate's cut-back wide from close range.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The point extends Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, and takes them a significant margin clear of the drop zone.
For the Manchester United though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Misfire Again
With the AFCON reaching its knockout phase, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team's squad.
It's not that the missing pair are the answer to all of United's problems. After all, they were part of the side that experienced poor results earlier in the campaign.
But without them, Amorim has few attacking options.
He evidently does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Dutch forward provided the through ball for Cunha's equaliser almost immediately 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 Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their fiercest rivals to Elland Road was a bit drab affair.
True, there were moments of expected fervor, but the hostile edge was not as pronounced as in previous encounters.
Leeds' fans were more concerned about their side's inability to get sustained possession in advanced areas for any length of time.
The striker's header that struck the post was an isolated moment of quality in a congested first half.
It still felt as though the hosts were finding it tough when a mistake opened the door for Aaronson.
Ever so briefly, Leeds' delirious fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now masterminding clear improvement.
The task is not done yet but gradually, Leeds are getting nearer to achieving their survival.
What Happens Next?
The Yorkshire club have a top-flight 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 FA Cup journey with a home tie.
