Key Moments
- Dominic Calvert-Lewin sees a early header ricochet off the post.
- Brenden Aaronson fires the home side ahead with a well-placed strike in the second half.
- Cunha responds only three minutes later.
- The Yorkshire side extend their longest Premier League unbeaten run since 2001.
The Red Devils' poor recent struggles persisted at Elland Road, but head coach the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more disappointment against Leeds.
The Everton loanee directed a first-half effort against the post for the in-form hosts before the American midfielder finished superbly with a low, 62nd-minute effort.
At that stage, the United boss was under intense scrutiny after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had two days less to recover, the forward restored parity three minutes later when he latched onto a pass from substitute the Dutchman and guided a finish underneath advancing Leeds goalkeeper Lucas Perri.
It was only the South American'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 mix of fitness issues and national team commitments.
Not that Leeds to sympathise with that given their own tight schedule.
The Swiss attacker forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and United heads were in hands when the Slovenian striker, 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 match, also fired against a post in the dying moments.
The draw extends the home side's unbeaten run to seven games, their best such streak since over two decades ago, and takes them eight points clear of the relegation zone.
For the Manchester United though, it was yet another chance to move into fourth spot, albeit only for a matter of hours, squandered.
Manchester United Breakdown: Amorim's Side Misfire Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be understood for hoping the participating nations make a pretty quick exit.
Current injuries to captain 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 answer to all of the club's problems. After all, they were part of the side that suffered poor results earlier in the campaign.
But without them, Amorim has few alternatives in attack.
He evidently does not trust teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost instantly after his introduction as a replacement.
That leaves Cunha, who has now scored three goals in five games, and others playing out of their natural positions, alongside Benjamin Sesko.
On this showing, the expensive frontman looks similar to previous struggling 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 young striker.
Leeds United Breakdown: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their fiercest rivals to home was a bit drab affair.
True, there were instances of typical fervor, but the intimidating edge was not as pronounced as in previous encounters.
Leeds' fans were more concerned about their side's struggle to get sustained possession in advanced areas for any prolonged period.
The Calvert-Lewin header that struck the post was an isolated moment of threat in a congested first half.
It still felt as though Leeds were finding it tough when a defensive error opened the door for Aaronson.
For a short moment, The home ecstatic fans thought they were about to secure a coveted win against Manchester United.
However, there is a wider context for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now masterminding significant progress.
The job is not completed yet but step by step, Leeds are getting nearer to securing their survival.
What Happens Next?
The Yorkshire club have a top-flight trip to Newcastle in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a league trip to Burnley before also beginning their cup journey with a home tie.
