Key Moments
- Dominic Calvert-Lewin sees a first-half header ricochet off the upright.
- Brenden Aaronson fires the hosts ahead with a low finish in the second half.
- Cunha responds just three minutes later.
- The Yorkshire side continue their best Premier League undefeated streak since 2001.
The Red Devils' disappointing run of form continued at Elland Road, but manager Ruben Amorim had his Brazilian forward to thank for the team not suffering even more disappointment against their old rivals.
Dominic Calvert-Lewin headed a first-period effort against the post for the in-form hosts before the American midfielder finished superbly with a driven, 62nd-minute shot.
At that stage, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
However, against opponents who had two days less to prepare, Cunha restored parity three minutes later when he latched onto a through ball from substitute the Dutchman and guided a finish underneath rushing 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 Amorim is without several key attacking players due to a combination of fitness issues and national team commitments.
Not that Leeds to care about that given their own lack of preparation time.
Noah Okafor forced a diving save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned Zirkzee's cut-back wide from close range.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also blasted against a post late on.
The draw prolongs the home side's unbeaten run to seven matches, their longest such streak since 2001, 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.
Manchester United Breakdown: Amorim's Side Struggle Again
With the AFCON reaching its knockout phase, Amorim could be forgiven for hoping the involved countries make a swift exit.
Existing injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team's options.
It's not that the absent players are the solution to all of United's problems. After all, they were part of the side that suffered poor results earlier in the season.
But without them, the boss has few attacking options.
He evidently does not have full faith in youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost immediately after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous underwhelming signings, lacking in confidence and assurance in front of goal.
His failure to turn home the cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Survival
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of expected atmosphere, but the intimidating edge was not as evident as in other encounters.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in dangerous areas for any length of time.
The striker's header that struck the post was an rare moment of threat in a congested first half.
It still felt as though Leeds were struggling when a defensive error opened the door for Aaronson.
Ever so briefly, The home delirious fans thought they were about to secure a rare 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 season, many speculated about the manager's future.
Instead, he is now overseeing clear improvement.
The job is not done yet but gradually, Leeds are getting closer to securing their top-flight status.
Looking Ahead
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. Manchester United face a league trip to Burnley before also entering their cup journey with a Old Trafford tie.
