Key Moments
- Calvert-Lewin sees a early header come back off the post.
- Aaronson puts the hosts ahead with a well-placed finish in the second period.
- Cunha levels only three minutes afterwards.
- Leeds continue their longest Premier League unbeaten run since the turn of the century.
Manchester United's poor run of form persisted at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more damage against Leeds.
The Everton loanee directed a first-half attempt against the woodwork for the in-form hosts before Brenden Aaronson applied a cool finish with a low, 62nd-minute shot.
With the goal, Amorim was in the firing line after his side had failed to beat struggling Wolves at Old Trafford earlier in the week.
Nevertheless, against a team who had two days less to prepare, Cunha restored parity three minutes later when he ran on to a pass from substitute Joshua Zirkzee and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his high-profile summer move and came at a time when Amorim is without four key attacking players due to a mix of fitness issues and national team commitments.
Not that you would expect Leeds to care about that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and United heads were in hands when Benjamin Sesko, who is finding it hard to make an impact, turned his teammate's cut-back wide from six yards out.
The goalscorer, who had a goal disallowed for offside much earlier in the contest, also fired against a post late on.
The point prolongs Leeds' unbeaten run to seven matches, their best 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 opportunity to move into the Champions League places, albeit only for a short time, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, Amorim could be forgiven for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only exacerbated the impact the unavailability of other attackers is having on Amorim's options.
It's not that the absent players are the solution to all of the club's problems. After all, they were part of the side that experienced disappointing results earlier in the season.
But without them, the boss has limited attacking options.
He clearly does not trust youngster Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the assist for Cunha's equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others operating out of their natural positions, alongside 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 a long run without a goal for the new signing.
Leeds Analysis: A Further Step Towards Safety
After memorable victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of expected fervor, but the intimidating edge was not as evident as in previous fixtures.
The home fans were more concerned 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 quality 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.
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 speculated about the manager's future.
In contrast, he is now masterminding significant improvement.
The job is not completed yet but gradually, Leeds are getting nearer to securing their survival.
What Happens Next?
Leeds have a top-flight trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Turf Moor before also entering their FA Cup journey with a Old Trafford tie.
