Match Summary
- Dominic Calvert-Lewin sees a first-half header ricochet off the post.
- Aaronson fires the hosts ahead with a well-placed strike in the second half.
- Cunha levels just three minutes later.
- Leeds extend their longest top-flight unbeaten run since 2001.
The Red Devils' poor 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 disappointment against their old rivals.
The Everton loanee headed a first-half attempt against the post for the in-form hosts before the American midfielder finished superbly with a low, 62nd-minute effort.
With the goal, Amorim was under intense scrutiny after his side had been held by struggling Wolverhampton Wanderers at Old Trafford earlier in the week.
Nevertheless, against opponents who had less time to prepare, Cunha levelled three minutes after the opener when he ran on to a through ball from substitute the Dutchman and slid a finish underneath rushing Leeds goalkeeper Lucas Perri.
It was only the South American's fourth goal since his high-profile summer move and came at a time when the manager is without several key attacking players due to a combination of fitness issues and national team commitments.
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 spectacular overhead kick, and visiting heads were in hands when the Slovenian striker, who is struggling to make an impression, turned Zirkzee's cut-back wide from six yards out.
Cunha, who had a goal disallowed for offside much earlier in the contest, also fired against a post in the dying moments.
The draw prolongs 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 matter of hours, wasted.
Manchester United Breakdown: Amorim's Side Struggle Again
With the Africa Cup of Nations reaching its latter stages, the United coach could be forgiven for hoping the involved countries make a pretty quick exit.
Current injuries to skipper Bruno Fernandes and Three Lions star Mason Mount only heightened the impact the absence of other attackers is having on Amorim'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 experienced poor results earlier in the campaign.
But without them, the boss has few attacking options.
He clearly does not trust teenager Shea Lacey or the much more experienced Joshua Zirkzee, even though the Netherlands forward delivered the through ball for the equaliser almost instantly after his arrival as a replacement.
That leaves Cunha, who has now scored a small tally in five games, and others playing out of their preferred positions, alongside Sesko.
On this showing, the expensive frontman looks similar to previous underwhelming signings, lacking in confidence and conviction 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 Analysis: Another Step Towards Safety
After memorable 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 expected fervor, but the intimidating edge was not as evident as in other encounters.
The home fans were more preoccupied about their side's struggle to get sustained possession in dangerous 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 struggling when a defensive error opened the door for the opener.
For a short moment, Leeds' ecstatic fans thought they were about to secure a coveted win against their old foes.
However, there is a wider context for the manager and Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many thought about the manager's position.
In contrast, he is now masterminding significant improvement.
The job is not completed yet but gradually, Leeds 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 league trip to Turf Moor before also beginning their FA Cup journey with a Old Trafford tie.
