Key Moments
- Calvert-Lewin watches a early header come back off the upright.
- Aaronson fires the hosts ahead with a low strike in the second period.
- Cunha responds only three minutes later.
- The Yorkshire side continue their longest Premier League undefeated streak since the turn of the century.
Manchester United's disappointing recent struggles persisted at Elland Road, but manager the Portuguese tactician had his Brazilian forward to thank for his side not suffering even more damage against Leeds.
Dominic Calvert-Lewin headed a first-period attempt against the post for the confident hosts before the American midfielder applied a cool finish with a driven, 62nd-minute effort.
At that stage, Amorim was in the firing line after his side had failed to beat bottom-of-the-table Wolverhampton Wanderers at home earlier in the week.
However, against opponents who had less time to prepare, Cunha restored parity three minutes later when he latched onto a through ball from introduced the Dutchman and guided a shot underneath advancing Leeds goalkeeper Lucas Perri.
It was only the Brazilian's fourth goal since his big-money 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 you would expect the hosts 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 United heads were in hands when Benjamin Sesko, who is struggling to make an impression, turned his teammate's cut-back wide from six yards out.
Cunha, who had a goal ruled out for offside much earlier in the contest, also blasted against a post late on.
The draw extends Leeds' unbeaten run to seven games, their longest such streak since over two decades ago, and takes them a significant margin clear of the relegation zone.
For the visitors though, it was yet another chance to move into fourth spot, albeit only for a short time, squandered.
Man Utd Analysis: Amorim's Side Struggle Again
With the AFCON reaching its latter stages, the United coach could be understood 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 unavailability of other forwards is having on Amorim's squad.
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, the boss has few alternatives in attack.
He evidently does not have full faith in teenager Shea Lacey or the seasoned Zirkzee, even though the Netherlands forward provided the assist for the equaliser almost immediately after his introduction as a substitute.
That leaves Cunha, who has now scored three goals in recent outings, and others playing out of their preferred positions, alongside Sesko.
On this showing, the big-money frontman looks no better than previous struggling signings, lacking in belief 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 Analysis: A Further Step Towards Survival
After thrilling victories in their previous home games, the arrival of their biggest rivals to home was a bit drab affair.
True, there were moments of typical fervor, but the intimidating edge was not as evident as in previous fixtures.
The home fans were more preoccupied about their side's inability to get worthwhile possession in advanced areas for any prolonged period.
The Calvert-Lewin 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, Leeds' ecstatic fans thought they were about to secure a rare win against Manchester United.
Nevertheless, there is a much bigger picture for Daniel Farke and Leeds to deal with.
When they endured a difficult run of form earlier in the campaign, many thought about the manager's future.
Instead, he is now masterminding significant improvement.
The task is not done yet but gradually, the team are getting nearer to achieving their survival.
What Happens Next?
Leeds have a top-flight trip to St James' Park in midweek, followed by the start of their FA Cup campaign next weekend. The Red Devils face a league trip to Burnley before also beginning their cup journey with a Old Trafford tie.
