Key Moments
- Calvert-Lewin sees a first-half header come back off the upright.
- Brenden Aaronson fires the hosts ahead with a well-placed strike in the second half.
- Cunha responds just three minutes later.
- The Yorkshire side extend their longest Premier League undefeated streak since the turn of the century.
Manchester United's poor recent struggles continued at Leeds' fortress, but head coach the Portuguese tactician had his Brazilian forward to thank for his side avoiding even more disappointment against Leeds.
Dominic Calvert-Lewin directed a first-half attempt against the woodwork for the in-form hosts before the American midfielder applied a cool finish with a low, 62nd-minute effort.
With the goal, Amorim was in the firing line after his side had failed to beat struggling Wolves at home earlier in the week.
Nevertheless, against a team who had two days less to recover, Cunha levelled three minutes after the opener when he latched onto a through ball from introduced Joshua Zirkzee and guided a shot underneath rushing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth Premier League goal since his high-profile summer move and came at a time when Amorim is without several key attacking players due to a combination of injury and international duty.
Not that Leeds to sympathise with that given their own lack of preparation time.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when Benjamin Sesko, who is struggling to make an impact, turned Zirkzee's cut-back wide from six yards out.
The goalscorer, who had a goal ruled out for offside much earlier in the contest, also fired against a post late on.
The draw extends the home side's unbeaten run to seven matches, their longest 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 the Champions League places, albeit only for a matter of hours, wasted.
Manchester United Breakdown: The Manager's Side Struggle Again
With the Africa Cup of Nations reaching its knockout phase, Amorim could be understood for hoping the participating nations make a swift exit.
Current injuries to skipper Bruno Fernandes and England international Mason Mount only heightened the impact the absence 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 disappointing results earlier in the season.
But without them, Amorim has limited attacking options.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the through ball for Cunha's equaliser almost instantly after his introduction as a replacement.
That leaves the Brazilian, who has now scored a small tally in recent outings, and others operating out of their preferred positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks no better than previous underwhelming signings, lacking in belief and conviction in front of goal.
His failure to turn home Zirkzee's cross means it is now a long run without a goal for the new signing.
Leeds United Breakdown: Another Step Towards Safety
After memorable victories in their last few home games, the arrival of their biggest rivals to home was a comparatively subdued affair.
True, there were moments of typical atmosphere, but the hostile edge was not as pronounced as in other encounters.
Leeds' fans were more preoccupied about their side's inability to get worthwhile possession in dangerous areas for any prolonged period.
The striker's header that struck the post was an isolated moment of quality in a tight first half.
It still felt as though the hosts were struggling when a mistake opened the door for Aaronson.
For a short moment, 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 difficult run of form earlier in the season, many thought about the manager's position.
Instead, he is now overseeing clear progress.
The job is not done yet but gradually, the team are getting closer to achieving their survival.
Looking Ahead
The Yorkshire club have a Premier League 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 Turf Moor before also entering their cup journey with a Old Trafford tie.
