Key Moments
- Calvert-Lewin watches a early header come back off the upright.
- Aaronson fires the home side ahead with a well-placed finish in the second period.
- Cunha levels only three minutes afterwards.
- Leeds continue their best Premier League unbeaten run since the turn of the century.
The Red Devils' disappointing recent struggles continued at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more damage against their old rivals.
The Everton loanee directed a first-half effort against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a driven, 62nd-minute shot.
With the goal, Amorim was under intense scrutiny after his side had been held by bottom-of-the-table Wolves at home earlier in the week.
Nevertheless, against a team who had less time to prepare, the forward restored parity three minutes later when he ran on to a through ball from substitute the Dutchman and slid a shot 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 you would expect the hosts to sympathise with that given their own tight schedule.
The Swiss attacker forced a diving save out of Manchester United goalkeeper Senne Lammens with a spectacular overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post in the dying moments.
The point extends 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 visitors though, it was yet another opportunity to move into the Champions League places, albeit only for a matter of hours, wasted.
Man Utd Analysis: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other attackers is having on Amorim'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 experienced poor results earlier in the season.
But without them, the boss has limited alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Joshua Zirkzee, even though the Dutch forward delivered the assist for the equaliser almost instantly after his arrival as a substitute.
That leaves Cunha, who has now scored three goals in five games, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks similar to previous struggling signings, lacking in confidence and assurance in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: A Further Step Towards Safety
After thrilling victories in their last few home games, the arrival of their fiercest rivals to home was a comparatively subdued affair.
True, there were instances of expected atmosphere, but the intimidating edge was not as pronounced as in previous fixtures.
The home fans were more preoccupied about their side's struggle to get worthwhile possession in advanced areas for any prolonged period.
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 finding it tough when a defensive error opened the door for the opener.
For a short moment, Leeds' delirious fans thought they were about to secure a coveted win against their old foes.
However, there is a wider context 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 position.
Instead, he is now overseeing significant improvement.
The job is not completed yet but step by step, the team are getting nearer to securing their survival.
What Happens Next?
Leeds 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 Burnley before also entering their cup journey with a Old Trafford tie.
