Key Moments
- Calvert-Lewin sees a first-half header ricochet off the post.
- Brenden Aaronson puts the home side ahead with a well-placed strike in the second half.
- Cunha equalises only three minutes later.
- The Yorkshire side continue their longest Premier League undefeated streak since 2001.
Manchester United's poor recent struggles continued at Elland Road, but head coach Ruben Amorim had his Brazilian forward to thank for his side avoiding even more damage against their old rivals.
The Everton loanee headed a first-period effort against the woodwork for the confident home team before the American midfielder finished superbly with a driven, 62nd-minute shot.
With the goal, the United boss was in the firing line after his side had been held by struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had less time to recover, Cunha levelled three minutes later when he latched onto a through ball from introduced Joshua Zirkzee and guided a finish underneath advancing home goalkeeper Lucas Perri.
It was only the South American's fourth Premier League goal since his big-money summer move and came at a time when Amorim is without four key attacking players due to a mix of fitness issues and international duty.
Not that Leeds to care about that given their own lack of preparation time.
The Swiss attacker forced a full length save out of visiting goalkeeper Senne Lammens with a audacious 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.
Cunha, who had a goal ruled out for offside much earlier in the match, also fired against a post late on.
The draw prolongs Leeds' unbeaten run to seven matches, their longest such streak since over two decades ago, and takes them a significant margin 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: The Manager's Side Misfire Again
With the AFCON reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a swift exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the unavailability of other forwards is having on Amorim's squad.
It's not that the absent players are the answer to all of United's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, Amorim has limited alternatives in attack.
He clearly does not trust teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost immediately after his arrival as a replacement.
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 similar to previous underwhelming signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home the cross means it is now nine games without a goal for the new signing.
Leeds Analysis: Another Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of typical fervor, but the hostile edge was not as evident as in previous encounters.
Leeds' fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any length of time.
The Calvert-Lewin header that clipped the post was an isolated moment of threat in a congested first half.
It still felt as though the hosts were struggling when a defensive error opened the door for the opener.
Ever so briefly, The home ecstatic fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they suffered a poor run of form earlier in the season, many thought about the manager's position.
Instead, he is now masterminding clear progress.
The job is not done yet but gradually, the team are getting closer to securing their top-flight status.
What Happens Next?
Leeds 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 Premier League trip to Burnley before also beginning their cup journey with a Old Trafford tie.
