Match Summary
- Dominic Calvert-Lewin sees a first-half header come back off the post.
- Brenden Aaronson puts the hosts ahead with a well-placed finish in the second half.
- Cunha levels only three minutes later.
- Leeds continue their longest top-flight unbeaten run since 2001.
The Red Devils' disappointing run of form continued at Leeds' fortress, but manager the Portuguese tactician had his Brazilian forward to thank for the team avoiding even more disappointment against Leeds.
Dominic Calvert-Lewin directed a first-half attempt against the post for the in-form hosts before Brenden Aaronson applied a cool finish with a driven, 62nd-minute effort.
At that stage, Amorim was under intense scrutiny after his side had failed to beat struggling Wolverhampton Wanderers at home earlier in the week.
However, against a team who had less time to prepare, 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 South American's fourth Premier League goal since his high-profile summer move and came at a time when the manager is without four key attacking players due to a mix of injury and national team commitments.
Not that Leeds to care about that given their own tight schedule.
Noah Okafor forced a full length save out of Manchester United goalkeeper Senne Lammens with a audacious overhead kick, and visiting heads were in hands when the Slovenian striker, who is finding it hard to make an impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the match, also fired against a post late on.
The point extends Leeds' 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 chance to move into the Champions League places, albeit only for a short time, 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 swift exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only exacerbated the impact the unavailability of other forwards is having on the team's squad.
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, Amorim has limited attacking options.
He evidently does not trust teenager Shea Lacey or the much more experienced Zirkzee, even though the Netherlands forward delivered the assist for Cunha's equaliser almost instantly after his arrival as a substitute.
That leaves the Brazilian, who has now scored three goals in five games, and others playing out of their preferred positions, alongside Benjamin Sesko.
On this showing, the big-money frontman looks no better than previous struggling signings, lacking in belief and conviction in front of goal.
Sesko's failure to turn home Zirkzee's cross means it is now nine games without a goal for the new signing.
Leeds Analysis: Another Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to Elland Road was a bit drab affair.
True, there were moments of typical atmosphere, but the intimidating edge was not as pronounced as in other encounters.
The home fans were more concerned about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The striker's 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, The home delirious fans thought they were about to secure a rare win against their old foes.
However, there is a much bigger picture for the manager and the club to deal with.
When they suffered a difficult run of form earlier in the season, many speculated about the manager's future.
In contrast, he is now masterminding clear improvement.
The task is not done yet but gradually, the team are getting closer to securing their survival.
What Happens Next?
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their domestic cup campaign next weekend. Manchester United face a Premier League trip to Burnley before also entering their FA Cup journey with a Old Trafford tie.
