Match Summary
- Calvert-Lewin sees a early header come back off the upright.
- Aaronson puts the hosts ahead with a well-placed effort in the second period.
- Cunha responds just three minutes afterwards.
- The Yorkshire side extend their longest top-flight undefeated streak since 2001.
Manchester United's poor recent struggles persisted at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period effort against the woodwork for the in-form home team before Brenden Aaronson finished superbly with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had two days less to recover, Cunha restored parity three minutes after the opener when he latched onto a through ball from substitute the Dutchman and guided a shot 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 Amorim is without several key attacking players due to a mix of fitness issues and international duty.
Not that you would expect the hosts 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 Benjamin Sesko, who is struggling 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 match, also fired against a post in the dying moments.
The point prolongs the home side's unbeaten run to seven games, their best such streak since 2001, and takes them eight points clear of the drop zone.
For the visitors though, it was yet another opportunity to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the participating nations make a swift exit.
Current injuries to captain Bruno Fernandes and England international 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 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 few alternatives in attack.
He clearly does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the through ball for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous struggling signings, lacking in belief and conviction in front of goal.
His failure to turn home the cross means it is now a long run without a goal for the young striker.
Leeds Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of expected atmosphere, but the hostile edge was not as evident as in other fixtures.
Leeds' fans were more preoccupied about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The Calvert-Lewin header that clipped the post was an isolated moment of quality in a tight first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
Ever so briefly, The home ecstatic fans thought they were about to secure a coveted win against their old foes.
Nevertheless, there is a wider context for the manager and the club to deal with.
When they endured a difficult run of form earlier in the season, many speculated about the manager's future.
Instead, he is now masterminding significant progress.
The job is not completed yet but step by step, the team are getting closer to securing their survival.
Looking Ahead
The Yorkshire club have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a league trip to Turf Moor before also entering their FA Cup journey with a home tie.
