Key Moments
- Calvert-Lewin sees a first-half header ricochet off the post.
- Brenden Aaronson puts the hosts ahead with a low strike in the second half.
- Cunha levels only three minutes later.
- Leeds continue their longest Premier League undefeated streak since the turn of the century.
The Red Devils' disappointing run of form continued at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for the team not suffering even more damage against their old rivals.
Dominic Calvert-Lewin directed a first-period attempt against the woodwork for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had been held by struggling Wolves at home earlier in the week.
However, against a team who had two days less to prepare, the forward restored parity three minutes after the opener when he ran on to a pass from introduced Joshua Zirkzee and guided a shot underneath rushing home goalkeeper Lucas Perri.
It was only the South American'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 combination of injury and national team commitments.
Not that the hosts to sympathise with that given their own tight schedule.
Noah Okafor forced a full length save out of visiting goalkeeper Senne Lammens with a spectacular overhead kick, and United 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 match, also blasted against a post late on.
The draw prolongs Leeds' unbeaten run to seven matches, their best such streak since 2001, and takes them eight points clear of the relegation zone.
For the visitors though, it was yet another chance to move into the Champions League places, albeit only for a matter of hours, squandered.
Man Utd Analysis: The Manager's Side Misfire Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the participating nations make a pretty quick exit.
Existing injuries to captain Bruno Fernandes and England international Mason Mount only heightened the impact the absence of other forwards is having on the team'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 disappointing results earlier in the season.
But without them, Amorim has few attacking options.
He clearly does not have full faith in teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward delivered the through ball for Cunha's equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored three goals in recent outings, and others playing out of their natural positions, alongside Sesko.
On this showing, the big-money frontman looks similar to previous underwhelming signings, lacking in belief and assurance in front of goal.
His failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds Analysis: A Further Step Towards Survival
After memorable victories in their last few home games, the arrival of their biggest rivals to Elland Road 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 concerned about their side's inability to get sustained possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an rare moment of quality in a tight first half.
It still felt as though Leeds were struggling when a defensive error opened the door for Aaronson.
Ever so briefly, The home ecstatic fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a wider context for Daniel Farke and Leeds to deal with.
When they suffered a difficult run of form earlier in the campaign, many speculated about the manager's position.
In contrast, he is now overseeing clear progress.
The job is not done yet but step by step, Leeds are getting closer to securing their top-flight status.
What Happens Next?
Leeds have a Premier League trip to Newcastle in midweek, followed by the start of their FA Cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also beginning their cup journey with a Old Trafford tie.
