Match Summary
- Dominic Calvert-Lewin sees a early header ricochet off the post.
- Aaronson fires the home side ahead with a low effort in the second half.
- Cunha levels just three minutes afterwards.
- The Yorkshire side continue their best Premier League unbeaten run since 2001.
The Red Devils' disappointing run of form persisted at Elland Road, 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-period effort against the woodwork for the in-form home team before the American midfielder applied a cool finish with a low, 62nd-minute shot.
At that stage, Amorim was in the firing line after his side had failed to beat bottom-of-the-table Wolves at home earlier in the week.
Nevertheless, against opponents who had less time to prepare, Cunha restored parity three minutes later when he latched onto a through ball from introduced the Dutchman and slid a shot underneath advancing Leeds 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 the manager is without four key attacking players due to a mix of fitness issues and international duty.
Not that you would expect 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 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 close range.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The point extends the home side's unbeaten run to seven matches, 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 chance to move into fourth spot, albeit only for a matter of hours, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Existing injuries to skipper Bruno Fernandes and England international 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, Amorim has limited attacking options.
He clearly does not trust 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 substitute.
That leaves Cunha, who has now scored a small tally in five games, and others operating out of their preferred positions, alongside Sesko.
On this showing, the expensive frontman looks similar to previous underwhelming signings, lacking in confidence and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the young striker.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were instances of typical atmosphere, but the hostile edge was not as pronounced as in previous fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in dangerous areas for any length of time.
The striker's header that clipped the post was an isolated moment of quality in a congested first half.
It still felt as though Leeds were struggling when a mistake opened the door for the opener.
For a short moment, The home ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a much bigger picture for the manager and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's position.
Instead, he is now masterminding clear progress.
The task is not done yet but step by step, Leeds are getting nearer to achieving their survival.
What Happens Next?
The Yorkshire club have a Premier League trip to St James' Park 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.
